I would suggest looking at the Merlin TSM, which are in your budget. The ideal listening triangle for the TSM is 6.5 feet apart and the listening position 9-9.5 feet away. I have mine set about 1.5 from the wall (measured from the rear). Better yet they are a sealed design, which makes them easier to place in a small room. In my experience, even front ported speakers can introduce some "boom", especially if your placement options are limited. If you decide to go with a ported design, experiment with plugging the port for better integration.
I am using a Martin Logan Dynamo sub that works pretty well for the money, but there are better choices out there. I've been thinking of upgrading to a 10" Velodyne SPL or DD sub that reportedly have very good built in equiliaztion software that aids in room integration.
