Need to fix some tags......HELP please!!

My abum tracks have been playing in alphabetical order instead of numerical on my Zen Vision M, and I posted about it here, and I posted this problem at the EAC forums and was told, based on a few screen shots of some settings, that I was having the LAME and EAC tag the files.I didn't know that was happening, but apparently it did. I guess the tracks have 2 sets of tags?? Anyway, it was suggested that I fix the tags, but I would have no idea what to look for to fix, or how to look. I've used this program very little, and this sounds like something where I'd have no idea how to start. Any help greatly apprecioated! Thanks!
