Don't apologize, I'm pretty much new to the subject myself, and we all have to start somewhere and somehow.
Regarding muxing into Matroska (mkv), I believe its not supported by mencoder. It only has a demuxer (i.e. it can read) for that container type, but not a muxer (can not write). If it had one, your command line would anyway look like this "-o output.mkv -of lavf -lavfopts format=mkv". But as said I'm pretty much sure that's not supported.
Look at the output of your mencoder run. At some point early on it likely tells you that it muxes into avi (the default output container format) since your options make no sense to mencoder. That's also likely the cause your sound isn't muxed in, because avi doesn't support AAC.
Regarding b frames and avi I don't know, being not that proficient with this format myself.
