I started in this similarly, with a mixed bag of whatnot and no budget in mind. It's turned out that the budget is whatever I can get. As to suggesting equipment, that's tough since there are so many variables such as what you like, your music tastes, system goals, type of sound you enjoy from a system...
I have a friend who has been in the hifi biz for many years and knows my tastes. He's the only person who I trust when he says I'd like something. Even so, I have to hear something to see what it does.
I highly recommend going and listening to whatever you can. See if you can get a demo of 2 different amps at a hifi store. With the economy the way it is, many stores are happy just to have something to do. I'd explain that you're in a 'learning phase' and just want some understanding. Browse their used stuff and take note of it.
I have found much joy in this hobby, particularly 'the chase'. Researching and finding equipment can be fun. But, I think you should hear it instead of relying too much on advice from forums. You'll know your goals about a piece of your system once you've heard as few as 2-3 amps, subs, CD players, or etc. You'll know you like the smoothness of this or the roundness of that... warmth, brightness, control, imaging, etc.
As to a 1k budget... You can get 2 amps and a pre-amp with dual outs to truly biamp your speakers for under ~800 leaving you enough for a cheap DAC to boot. (Audible Illusions 2 and 2 B&K ST-140's, Haflers, or etc.) However, do you like the tube sound or the solid state sound? What do you like in a DAC?
I will admit DAC's and such are tough to hear in person sometimes... So, if you're looking for cheap, maybe a Soundstream DAC1... I sold one for $80 and it sounded pretty nice. Just to give a starting point.
Listen for what you like and you'll be able to ask better questions for gear choices down the road.
Good luck,
Carl
