Hi! Let me take a shot at some of your questions.
1. Well first off, where do i start? I have a Wii, dvd player, and a VHS player. What do I plug into the receiver? I have component cables for the Wii and the DVD player. Would i plug the component cables on the listed "component video, video 1 in" then plug the other plugs into the other "video 1" section? Diagram -

Would i not plug a cable into the yellow jack of the "video 1" section? Would i do the same thing for my DVD player? My VHS player is just the yellow, red, and white cords, so im sure i can do that.
Here's my suggestion based upon what you've told us:
1a. Connect the DVD component video (three plugs) into the receiver at the "COMPONENT VIDEO" section under "DVD IN".
1b. You'll want to use a digital audio connection between DVD player and the receiver, either optical or coax depending on what you have available. Let us know the model number of your DVD player, and we can give you more specifics.
2a. Connect the component video from the Wii into the receiver at the "COMPONENT VIDEO" section under "VIDEO 2 IN".
2b. Connect the analog audio (left/right RCA jacks) from the Wii into the receiver at the "VIDEO 2" section with the red and white inputs.
3. Connect the video and left/right audio outputs from the VCR to the "VIDEO 1" section on the receiver with the red and white audio inputs and the single yellow video input. I suggest using "VIDEO 1" for the VCR in case you decide to connect the audio and video outputs on the receiver under "VIDEO 1" to the audio and video inputs on the VCR at some point in the future.
2. In the diagram () In the "monitor out" section, there is a cable running from that to the TV. Where do i plug that cable into on my TV?

You will need to make two connections: one for the component video inputs, and one for the composite (yellow) video input from the VCR. This is because your receiver won't convert composite to component or vice versa. No big deal, it's just another cable to run. You'll want to look at page 6 of the TV owner's manual to which you linked for the following.
1. Connect the "OUT" jacks of the "COMPONENT VIDEO" section of the receiver to the component video jacks on the TV for either the "VIDEO2" or "VIDEO3" jacks. You need to select that input on the TV in order to watch the DVD player or the Wii.
2. Connect the "MONITOR OUT" on the receiver to the yellow jack of the "VIDEO1" on the TV. You'll need to select that input on the TV in order to watch the VCR.
3. I also got a coaxial cable, do i just plug that into my coaxial port on my TV and then plug that into the receiver?
Are you referring to the screw on cable from a cable provider or over-the-air antenna? If so, then yes - plug that into the TV. You could then connect the digital audio output from the TV (digital coax) to the digital coax input on the receiver - assuming that you didn't use that for the DVD player already (so, hopefully the DVD player has an optical digital audio output).
As far as cables are concerned:
1. Component video, composite video, analog audio, and digital coax will all use cables that have RCA connectors on the ends. Monoprice.com is a nice place to buy quality cables for a good price. You can get those cables at many places, though, such as Radio Shack, Target, or Home Depot.
2. Digital optical connections use an optical cable, like this one
