I really can't comment on the computer.
But I would recommend getting one of the Halcyon 3' SMBs. I really like them -- we've had about six different brands of bags, and the Halcyons are my favorite. They have an OPV, so you don't have to worry about overinflating them. You can inflate them orally, or from an LP hose. I dive cold water, and I find other bags difficult to inflate with cold lips, but the Halcyon bag has a flange on the metal inflator valve that makes it much easier to get a seal. They're expensive, and they're worth it. I don't recommend a lot of Halcyon stuff because of the price points, but the bags rock.
Get a nice Delrin finger spool to attach to it, and you're set.
Lights ARE all over the place price-wise, and a lot depends on what you want a light FOR, and where you are going to dive. If you want a light for tropical night diving, you don't need very much. Lighting up the underwater world like a movie stage just means all the really nocturnal critters have hidden long before you get to them. Clear water means you don't need much light, so small, backup-type lights work just fine.
If you are diving in low visibility, on the other hand, you want power and punch. Lights in that environment are a method of communication and keeping buddies together, and you almost can't have too much light. That's when you start getting into the canister lights and big price tags. Again, they are worth it -- I consider my primary light to be a major piece of safety equipment, and if I were going to choose between a fancy computer with a transmitter and a digital compass (and I have yet to see one of those that actually WORKS) and a simple gauge and some money toward a good light, I'd take the latter course.
