Lately I have been working alot on alternate picking. Things are going great, however I'm still having a little bit of trouble when descending. Mainly, finger independence and making notes sound flat because I don't lift my fingers up at the right time.

If anyone can recommend some exercises to address this problem specifically, I would appreciate it!

Usual thing, start slow and practise with a metronome at a speed you're comfortable with, then progressively speed up. If you start to get sloppy, slow down again.

I would advise you download this one (it's free) http://www.nch.com.au/metronome/index.html

That way you can use it when you're not on the internet, unlikely as it may seem :p
