i think it depends on the music you are looking to play. but whatever it is, you should keep working on your chords. try picking it up to a rather brisk pace. and work on playing them cleanly. be tough on yourself. if you hear a buzzing string, play it over again.
if you are playing harder rock, work on palm-muting your chords. do all downstrokes for better chunk though.
if you are wondering what to do next, dont worry about soloing. because judging by that question, you are a long ways from playing for an audience. work on everything else, then focus on solos.
