Look in the screen forums for screens. However, there seems to be good reviews on the Elite Sable, Jamestown and Visual Apex lines for entry level vinyl screens
Speakers are such a personal and religious experience that it is hard to advise. You will get lots of opinions, usually fanboy type raves and slams. This is the time of year that you can find bargains if you shop. For example, Best Buy had a good sale on the Klipsch towers a couple of weeks ago. One issue is that you have not provided a price point. A good tower speaker can be had for anywhere from $250 to $OMG. I can help you find some dandy fronts at $25k each.
For home theater and gaming, I would look at distributing the money spent as follows:
equal amounts on the main and center speakers. It is important that they match, so same brand and line.
Spend twice as much on the sub as you spend on each main speaker. The sub makes a big difference, and you want a good one. The sub seems to be the first speaker that people upgrade, so do it right the first time.
Spend half as much on the surrounds as you do on the mains. I would wire the room for 7.1, but would hold off on the speakers at first. The room is fairly small and the benefits are small. Put the money into better mains.
So, with a $2k speaker budget, I'd be looking at
$300/ea for Left, Right and Center\
$600 for the subwoofer
$150/ea for the surrounds
Total: $1800. I might put the extra $200 into the sub.
With careful shopping this would get you a good setup from brands like Klipsch, Polk, Definitive Tech, Mirage, etc. The only way to find the ones that are right for you is to go listen, but not at Best Buy. Their showroom floor with its 30' ceilings will not give you any sort of accurate idea.
