Actually I think you have a pretty good practice regime there!
Due to work, sometimes I don't get to practice as much as I like, but I usually try to incorporate a few things into my regime.
Rudiments and technique, (acts as a great warm up)
Reading.
Musicality in different styles.
Soloing.
Showmanship.
You can combine some of these into one exercise too.
For example take play along books and cd's. You are reading and practicing a style in one go. Whilst doing this you're improving your musicality in that style. Most have a solo section, which will really test your reading ability.
The other important thing to remember is to practice things you can't play easily, that's the only way to improve!
I also try and set myself a goal say 2 weeks to achieve a particular skill, weather its playing a 10 stroke roll or groups of 7 on the double bass drum while holding down a backbeat.
