Sounds like you have a very thorough, organised practice regime there. I'm jealous! :)

Yeah, if you haven't already mastered barre chords, focus on them. They are just so useful it's not funny, I am a chronic barre chord addict.
If you've got those down-pat, and you know all your major, minor, 7th, minor 7th chords, you might like to try out a few different styles of guitar playing. Rock, pop, jazz, folk, blues, metal, reggae, classical - they all have distinct technical approaches (rhythm and lead alike). Trying them out will help you work out which musical path you want to pursue. Ask your teacher about this, and perhaps some basic songs you could go through for each one. Here are a couple of basic "genre" songs I used when I was at this stage:

Rock: Nirvana - "Smells Like Teen Spirit"
Jazz: Dave Brubeck Quartet - "Take Five" (arranged for guitar)
Blues: John Lee Hooker - "Boom Boom Boom Boom"
Classical: Pachelbel's "Canon" (transposed to C Major)
Pop: Green Day - "Good Riddance"
Metal: Silverchair - "Freak"
For other styles, my teacher just came up with some basic riffs of his own for me to practice.

Hope all my blabbing helped a bit...
