Anytime Sunboost. I am pretty sure there is a special bios for people with the ultrabay. I think it is the 2.02.

Sunboost, I can tell you that the internal gpu and the cpu are on the same heatsink so you can do them both at the same time. The ultrabay gpu I honestly have no idea about taking it apart to do any work on it. I only had problems with the internal gpu and cpu.

I bought an msata Mushkin 120gb msata ssd and use the 1tb for storage. I know I can be in windows and restart my laptop and be back to my log-in screen in about 10 seconds. It was the best upgrade I made.

Repasting dropped my GPU temps by 10C and CPU temp by 15C under load. I'd say it was worth it.

No idea about your second question, but there's no point in testing with a Kill-a-watt as you'll reach a temperature limit on the GPU before you run out of juice from the 170 W brick. I ran my 650M SLI with 1260/2250 @ 1.137 V and it was reaching throttling temperature (97C) but the charger was able to keep up without draining battery, even when stress testing with OCCT PSU Test (basically 64-bit Linpack + a FurMark-like test simultaneously). Oh yeah and my CPU reached TJmax at 105C and shut down after a few minutes of this.
