If you are going to be using it for movies mostly, (and audio as a secondary use), I recommend getting a good HT receiver. There are lots of them out there that can work for both home theater as well as audio. This will allow you the maximum flexibility, and it will have the DTS, Dolby Digital and THX decoding that you will need should you ever decide to upgrade to a full blown 5.1 (or better) surround sound system. It can also serve, (temporarily, until you can afford to get a good stereo system), as an amp for listening to music.
My recommendation, and I know I buck most peoples opinion on this site, is that you should not try to combine audio and video, at least not in the price range you are in. (I also think that listening to movies in two channels is not nearly as good as listening in 5.1 - again, I am going against most people on this site, as least according to one of the threads started recently.)
(I have a decent HT receiver, a Denon 3802. However, it is not really all that great for audio, or at least it is not in the realm of what I consider to be high end. I can use it to listen to music, but only casually, not seriously.)
I also recommend you stick with SS, as it is less tweaky than tubes, and since you want to use it mostly for movies, you will probably want decent power and really good bass. Don't forget that you'll need an integrated amp, not just a power amp (or else you will need a preamp too.)
If you really want monitor type speakers, the M&K speakers are relatively inexpensive and yet are accurate and can play loud. (However, I consider them to be more for HT use, rather than for stereo use. I use the K7's and K4's in my system.)
My two cents on this matter mostly boils down to this:
If you are going to listen to movies, do it right and get a 5.1 surround sound HT setup.
If you are going to listen to music, do it right and dedicate a stereo for that alone.
These are, of course, my opinions. However, I know that most of my friends share them as well.
Good Luck in your quest!
