1) what gauge speaker wire should I use? each front tower is about 6 feet away from the receiver, and the surrounds are about 15 away, does It matter the brand? the local bestbuy carries Monster Xp speaker wire is that ok? or am i just buying the name brand.
There are a number of articles on it, but Monster Cable gives you no improvement over other cable. I would typically run 14 gauge, but you can likely run 16 gauge or thicker (14, 12, 10, etc.) if it makes you feel better about things. 100' is about 30 bucks plus shipping here:

2)what should my crossover be set to for the towers, centre, surround and sub fullband 80,90,100 etc.....
Does the Denon offer crossover settings for the towers? I think it is usually just 'small' or 'large' on the main speakers. The only use of a crossover is to determine the frequency that the subwoofer starts taking over for the main speakers and where the rolloff occurs. It is not typically done 'per speaker', but if this option is there, I would leave it at about 80hz as the subwoofer rolloff level.
3)speaker size all large or all small?
Small typically with properly matched speakers. Unless you have subwoofers in your speakers, then the low frequencies need to be handled by the subwoofer.
4)sub woofer setup Lfe+main or just lfe?
LFE+Main will allow the sub to handle all the low frequencies in your system and this is exactly what you want. LFE is ONLY the information that is on the LFE channel of the audio. This means that any low frequencies sent to the main speakers would be lost, and this is NOT what you want.
5)how about the setup on the subwoofer its self, Phase 180 or less? the low pass filtre 120hz or less or off and set it in lfe mode?
Set it to 0 and then run the auto-setup on the Denon, it'll handle that.
6)do banana plugs degrade sound quality or is it not worth getting banana plugs they are pretty expensive best buy sells monster banana plugs 28.99 for 2 pairs I find that very expensive.
Once again with the Monster machine.
How about these?

They double clamp the speaker wire so it doesn't fall out (ever) and the plastic cover helps to prevent shorts. Under 20 bucks and you are more than covered on what you need. You'll have a few left over to give to a friend in need.
7)and the last question is about the front towers should I just run a single speaker wire to each tower or remove the metal clips and run 2 wires for each tower? bi-amp i believe its called
Bi-amp is TWO AMPS running things. What you are talking about is bi-wiring. Or, as some prefer to call it BUY-wiring. It's a waste of money to run more wires and produces zero sonic improvement to your system.
1)isnt crossover supposed to be set based on the speakers you have? i mean shouldnt it be different for every speaker? plus what are you listening for when adjusting the crossover the more clearer the better? should the volume be loud when adjusting by ear?
You typically don't adjust by ear. The crossover is the point at which you want to remove bass from the speakers which can't handle them (all of yours) to the speaker which can handle it (the subwoofer). With properly matched speakers, this point of 'crossover' is going to be the same on all speakers. You want it the same because it helps to match the sound coming from all the speakers. So, instead of a couple of speakers reaching a bit lower than others, you get very similar sound from every speaker in the room.
2)now there are adjustments that the built in amp on the sub has phase and low pass filtre and the lfe mode if i have the receiver set to lfe should i set the sub to lfe? i ask this because if i set it on the receiver i still have to go to the sub and adjust the low pass filtre so should they both be set to lfe?
Set the subwoofer to LFE and set the crossover on the subwoofer high - 120hz, or 160hz or whatever it's highest setting is. Basically you are telling the subwoofer to accept whatever signal is coming into it and the place to look for that signal is on the LFE input. This is correct since the Denon will be what is handling the bass for the subwoofer.
3)I wanted to buy the speaker wire today and i have no idea were to buy blue jean or monoprice cable. any recommendations for big box store brands.
I bought my receiver at small high end audio store here in Toronto(canada) called Bay Bloor Radio they have speaker wire im not sure the brands but its all super expensive they had wire there at almost 6bucks per foot im sure its great wire but i cant spend that kind of money on speaker wire.
No, it's wire. It is NOT great wire! It's NORMAL wire and it's overpriced by $5.70 a foot!
You can pick up cheap speaker wire quite often from your local hardware store. They typically have speaker wire (at least in the US, Home Depot and Lowes carries speaker wire), but even THAT is expensive. Going online to buy cable gives you quality cable for far less than stores will be selling it for, and it's unfortunate that you didn't ask these questions a week or so ago because you could have ordered and had the stuff already. At this point, you are just going to end up wasting money to have it right now.
Not that I don't understand that eagerness to get things setup. It's pretty darn exciting to have new gear.
