I had a storage/work shed built in my backyard. I'd like to run two 20-amp circuits to it. The distance from the fuse panel to the shed is between 100 and 120 feet.

1) What gauge wire do I need?
2) I assume I need to bury the lines, what do I need for conduit?

according to 215-2, you need a 30 A minimum conductor. this would be #10 wire. this could be done in UF , or in pipe with THWN/THHN ( rated for wet location) in 3/4" pvc ( ease of pull.
if this is a multiwire branch circuit ( shared neutral, as in the 10-3 UF ) , then 250-32 EX would allow you to get away without a G-rod(s).
Generally, if it terminates in OCPD ( breakers or fuse panel) you MAY need a G-rod ( I would let AHJ make the call here)
Being that it must be fed via 30A 2-pole, and be fused down for the 2 -20A branches, a small sub-panel is in order here.
