First?? That is pointoless for 2 reasons...
You dont need to root to flash with odin
Root will be gone after you flash rom in odin.
If the user wants root he should flash custom kernel after flashing rom.

Is it okay to jump from Gingerbread 2.3.5 to Jelly Bean 4.1.2 or should I flash 4.0.3 first?

If you don't know the basics, perhaps you shouldn't mess with flashing.
First read, learn and understand rooting, Odin, ADB, brick-bug, kernels and ROMs, bootloops and bricks.
When you think you're ready, you'll already know the anwers.
