First, I have no way of knowing what "Blah." Is. And you didn't say specifically which sensors you're referring to. "Coolant/Throttle Body" are two different things, and there are many different sensors.
The coolant sensor is (Usually) located right on top of the thermostat housing. But even if it's in another location, it is very simple to take that off. You can probably go to you neighborhood parts store and ask them to locate it's position for you, and also rent you the socket necessary to unscrew it. (Takes 30-seconds) A mechanic may charge you $20-$40.
The "Throttle Position" sensor is something a bit more complicated. I wouldn't try to tackle that yourself. Though it's simple to remove the bolts holding it in place, there is a spring inside that has to be inserted correctly in order for it to function. Labor for this shouldn't exceed $100.
As far as your fuel pump, that's located inside of your gas tank. If you aren't mechanically inclined, I would recommend you do this either. (Dangerous!) Labor for this can be anywhere from $100-$200.
