I tend to agree with the couple of posts above. I'm a believer in working from your front end to the back, and I definitely include room treatment as part of your front end.
You don't really have what I would consider a solid workhorse condenser mic. Something like a KSM44 or an AT4050. A quality pair of SDC microphones or do two 4050's or two KSM27's or KSM32's for drums. For budget mics I'm a fan of Shure and Audio Techinica myself and not so much of a lot of the other crap that's out there.
A good mic, pre and quality AD is much more important to me than high end monitors, initially. If your room is treated you can learn to mix well in that environment. If you have a good room, good mics, good pre, good AD, etc. you get the picture. Once things are captured well that part of the equation is done.
I've mixed on pretty cheap monitors and been able to get things to translate pretty well after listening on different systems. Good luck.
