Thanks a lot. That information helped out a bunch. Could you tell me what exactly the Pre-amp is for? I will continue to research and definitely try to find some places where I can listen to stuff first.
A preamplifier is also sometimes called a "control amplifier". It is used for switching between various inputs, adjusting the volume, and typically (though not always) has tone controls. Typically, a preamplifier can slightly amplify a signal to get it at an appropriate level for a power amplifier to use. (The power amplifier is what drives the speakers.)
You may or may not need a preamplifier, based upon what else you are using, and what you want to be able to do. But unless you are sure you don't need one, you will want to leave enough money in your budget to be able to buy one.
A receiver is a tuner (radio), preamplifier, and power amplifier, all in one box.
An integrated amplifier is a preamplifier and power amplifier in one box.
The quality of each is not determined by whether it is all in one box or in several boxes. Either way can be fine, and either way can get you garbage.
Obviously, if you bought an integrated amplifier or a receiver, you will have purchased a preamplifier, and therefore need not budget money for another preamplifier, unless you wanted one that could do something that the built in preamplifier could not do.
It is generally best to select one's speakers first, and then select appropriate amplification for it. The reason is that some speakers require more power than others, and some speakers are harder to drive (i.e., lower impedance) than others. However, the power amplifier I suggested previously is inexpensive for what you get, and will drive most speakers more than adequately. Still, select your speakers first, just in case.
If you had tons of money to spend, given what you have said about what you want, I would suggest some very high end Klipsch speakers, such as the Klipschorn or the La Scala:

Or the discontinued Belle Klipsch:

You might be able to get a used pair within your budget, but you will be lucky to be able to do so. With any of the above, ANY decent amplification would be adequate for deafening levels of sound.
One of the downsides of the above speakers is that they are large and heavy. Typically, this means you must buy locally, and you must have a truck to get them home.
