I'm running on an AFM engine. I have the TPS on order, it's on it's way down here. How would i check the TPS? I wouldn't have the slightest clue on how to make sure it's working correctly etc.

TPS can be checked with a multimeter- you should try to get hold of/borrow the TSRM (toyota service repair manual) for your engine - it will have a number of testing methods
in a nutshell, if it's a variable resistance TPS you measure the resistance between centre and an outer pin (3 pins on plug?) and the resistance should vary as you move the throttle. one pin might be a WoT signal that only closes at near WOT.
if it's a switch, (usually 4 wires) various contacts will open/close as the throttle moves from closed to WoT -manual is needed to refer to switch behaviour

What do you mean by the spark?

beg/borrow a timing light (it will have power plugs + & - 12V and a clamp-thing to clamp around the #1 plug lead
read instructions that come with light (it basically flashes a strobe light when it senses a spark plug firing)
locate on front engine pulley and timing cover the timing marks
when you rev the engine, the timing will change (as shown up by the timing light) - unless the igniter is in limp home mode (it will stay at 10 degrees)
