Brian, based on what you say, I would say that you need to focus on setting up the room to optimize its performance for tracking (unfortunately, for most small rooms, you'll need to invest some time/cash into room treatment). Another suggestion would be to really focus on what things are sounding like when you're recording. Record a bit, listen back, and make adjustments based on what you're hearing. Fixing problems in the mix is no fun. Record often, experiment, and listen. If you really learn where in the room your instruments sound best, and which mics work for different sources, and the best positions for your mics, your recordings will come a long way.
