I never met a scale I didn't like.
Seriously though, thanks to the wonders of the Internet, that are a plethora of sites out there that have oodles of info on the scales, sweeps, etc., etc. Do a search on Google and being to blow your mind.
Also, be sure to learn the theory behind scales, modes and arpeggios. They are all just tools and if you don't know the theory behind them, you will never be able to use them to their fullest.
