Is there a good place to look up how much mass a given rocket can/could send to lunar orbit?

not sure, it depends upon so many factors. Did you have specific real-world rockets in mind, or were you trying to rough out a design on your own? Delta-V is the key. You'll need about 9.4 kilometers per second to get from surface to orbit and 8 km/s from there to lunar orbit

I actually just need Saturn, and just realized all I need to look up is the lunar lander mass! Or I guess that plus the weight of two astronauts.

The Department of Pedantry requires me to point out you need to look up: Loaded mass of LEM, plus mass of CM & SM, minus whatever fuel used for lunar orbital insertion.

Pedantry squared: remember that the third stage was sent to the moon too, and crashed there, so first / second / third stage burns did more than merely get LEM / CM / SM to the moon - broguht an extra 10,000 kilos! Brought no fuel with which to put 3rd stage into orbit tho
