If they really could do 2000 lbs to LEO, what does that translate to

Depends on what kind of upper stage and landing equipment, but I've
always used a factor of 7 as a rule of thumb. So 2000 / 7 would be
285 lb to the lunar surface.

About 6 with LOX/LH2 and about 7.5 with LOX/Kerosene seems possible.

LOX / Kerosene will be much more cost effective, especially for large
scale efforts involving multiple launches. That's why NASA's gone for
LOX/LH2.

BTW - I don't think a pure solid rocket could get any meaningful
payload even to orbit. Certainly not a single stage solid.
