Having lighter strings does help you play faster, but when you couple that with a scalloped fretboard, they kind of cancel each other out IMO; it takes a LOT of practice to play a scalloped fretboard like it's a normal fretboard, and it'll be that much harder if you have really, really light strings.

I'd recommend just really low action and light strings, and possibly a fret dressing, but definitely nothing more than that.
