It has a valve on it that you twist to open or close it, so it's easy to control how much oil you're dumping in. I think I got it at an advanced auto, or maybe even wal-mart. Anyway, I always put the oil in after I fill up with gas.

I have the same thing, and yes it was at advanced auto parts; however a small long funnel is far easier. Basically, I have the advanced auto part device, a small long funnel, and two 16oz (Penzoil yellow bottle from walmart or kmart) at all times on the car.
The worst part is cleaning the funnel afterwards

Which is why I used a pen to hold open the flap door in the filler neck.

yup, tcw3 from the auto store.
i carry about 3 32oz bottles at most.
fill up gas, poor in 1 oz per 1 gallon as pump meter tells me. close cap, clean up with paper towels at gas station and head out. no tools needed for me, just poor into hole. flapper seems to let in the oil without me moving it.
also, i have only been able to fill 15 gallons maximum. can't imagine jspec engines filling up differently if the tank is the same as aspec

Why would you need to premix the gas? I've ridden dirtbikes and I know two strokes need gas premixed but why would a rx7 need to be.

Check out those sites. The apex seals have combustion chamber on either sides, and run along the rotor housings, so they need some form of lubrication. The stock setup from Mazda has oil injection, but some people don't like the problems associated with the system after 20 years of age, they may say it doesn't lubricate well enough, or they don't like how it consumes the already-used engine oil. Premixing gaurantees lubrication all across the apex seal, and eliminates the stock oil metering system.
There are other points, and some may argue against what I post, but that's the main idea.
