Although I haven't yet listened to the track you provided, I have a few comments. First off, you might want to go in order, instead of doing your favorites first. It will help you in the long run, especially when you can do something like provide a zip for each finished group. Second, try uploading the music to a streaming server. That way, the people who don't want to bother downloading the music to see if it's worth anything can just listen to it online first. Finally, I can't help but wonder what you need all those programs for. I mean, can't you just import the midi file into Garritan, and then use Fruity Loops to check the instruments they used?
Edit: I just listened to the track, and I have a few more comments:
First, why is it so quiet? I have a laptop that has default volume so loud that I have to keep the Master Volume at one point above muted, (and some things are still too loud) and your track is barely audible in comparison. Next, I know you're using a professional program, but I don't think you made the best choices in instruments. The entire track sounded somewhat off, especially the drums. In fact, I think I may have preferred the instruments in the midi. Try messing around with theh intruments, and see if you can get it to come off a little better. And, if the Churh Organ in Garritan is anything like one in real life, you're pretty much screwed when it comes to Boss04. (Let's just say the church organ in a midi file is completely different from one in real life, and is used differently in the RMXP midis than a real one would be used. Not to mention the fact that it is impossible to have three in one room, with how they have to be built with a special room matched to their acoustics)
Here's an example of 001-Battle01 that I just uploaded, to show what I mean. It isn't perfect, but it has a more reasonable volume, it has a better instrument choice, and, as far as I can tell, it sounds much better than the original midi file. (Note: Link removed by Glitchfinder)
