It's not the number of UV co-ords. Light mapping in Giles automatically sets your base mesh to 'full bright' and then adds the lightmaps. I don't remember exactly right now but I think you can have upto 8 sets of UV co-ords in Blitz.
As for the faked spot light effect. I think Fredborg did a nice piece of code for that effect. I don't know if it's in the code archives though but he definitely had it on these forums somewhere.
