On memorising frets, I've used cards that have the fret number on one side and then the notes of the 6 strings in order on the other - that seems to work...
On scales check out the lessons here, probably starting with the pentatonics.
Speed will come dude. Play to a metronome/drum/click/whatever and concentrate on clean rather than fast, and you'll get there. No matter what the software says, there are no shortcuts. If you want to play like a demon you're going to have to practice... a lot. :cool:
