Since you are using RealTracks and RealDrums, you didn't indicate whether you used the audiophile versions (true WAV files) or the standard version (WMA files, which can be converted to WAV, but are still lossy audio from the original audiophile WAV's).

If using the WMA files, then by creating MP3's, you are re-compressing the files and losing additional fidelity from files that had already lost some fidelity when they were originally converted to WMA. So my recommendation would be to use either the WAV files themselves (which is the best you'll get), or convert to higher rate (256 or 320). While 192 makes pretty good MP3's, there is still an audible difference between that and the higher rates (do a side-by-side comparison and you'll hear it). Of course, your audience may never know or care.

Secondly, I find it easier to mix the balance using RealBand rather than in BIAB. You have a lot more control and can use additional effects on a track-by-track basis, as well as the overall mix.
