If you practice clean and slow and then add speed then you'll get the speed before you know it.
As far as mixing things up make sure and record yourself with the chord progs you want to work with and have at it. IF you can go ahead and record your solos too and compare. I've recorded my stuff for years and listen to the recordings over and over and over listening for spots to try different licks, what fits and what doesn't.
But practice. Can't substitute time at the strings.
