This should be where the waste line from your filter enters you sewer system, to prevent sewer gasses from entering your pool plumbing.

Is there a special type of p-trap needed for the pool side of things? Running down to the local big box, I see PVC P-traps for $3-5, and more expensive metal ones for $15-20.
A plain jane pvc one would most probably fit the requirements, but check with the city inspector.

2. Electric Valve - Return leaks at stem, but valve okay.

Is this a simple o-ring repair, or something more? Again, where can I find this?
Depends on the type of valve. Some have a special packing around the stem, others have an O-ring.

3. Gas Branch Line - no sediment trap. I'm familiar with sediment traps, but where would I find this in the system (my pool is heated). This appears to be a gas line related item, but is it something I should even worry about? And if so, where do I find the parts? Seems like it would be in the plumbing section, do I just need to sort out the right pipe connections/angles?
This is usually a stub set on a Tee, below the valve outside the heater, capped off to collect any sediment that might make it's way into the control valve. It is there to protect the control from any debris/condensation in the gas piping.

4. No GFCI on pump motor. I'm familiar with GFCI outlets, but is this something I can install, or is something I'm going to need a pool or electrical contractor for? I understand electrical safety, but this still makes me a little skittish.
Best bet is to hire an electrician familiar with pool wiring, and have him do a complete inspection of the pool's electrical system. There may be other problems that have gone unnoticed.

5. Spa light leak. I've found several step by step guides on pool light replacement. The pool inspector noted there's water in the unit.

Would that imply the entire light fixture is ruined, or can I maybe get away with draining the water and replacing the gasket seal on the light? Or am I in for a new light as well?

The question here is more about troubleshooting. There's a big gap between buying a new fixture, and replacing a gasket and/or light. Can I start small on this, or just move to the fixture replacement if there's water in the unit?

6. Final question (whew...). The spa remote is not responding. It's a Compool CP3600 Spa-side remote.

This appears to be this item:

How hard is it to replace this? Anything to be careful of?

Thanks in advance.

Working on a separate battle plan to address the algae currently in the pool :-/
The rest of the questions will have to be answered by others more knowledgeable in those areas, as well as any corrections to what I've answered.
