Like you, I'm learning this shit by the seat of my pants, so bear with me - that being said, I *think* I can answer your questions (but please JG or JK correct me if I'm wrong).
1) To figure out your true PSI, you'd need one of these:

2) Your real flow rate you could estimate pretty well (post #18 from the link above has the mathematical breakdown, but it's pretty simple to figure out), but you'd have to account for some variables that the equation can't (distance, loss, etc.)
3) Can't help you on the regulator question
4) See #2 above..........figure out how many GPM will flow through your nozzles at a given PSI, then match that to a pump that can/will output roughly that amount (a little more is better, methinks) at that pressure.
Again, let me reiterate that's my understanding, but someone could correct me if I'm wrong.........
bobby i have been reading that thread and it def helps alot. I now have new questions hahah. For this example im going to use some imaginary made up numbers.
PUMP
0.91 gpm @ 70 psi,
0.81 gpm @ 80 psi,
0.67 gpm @90 psi,
0.38 gpm at 100 psi
Nozzles
@70 psi .0159 gpm per nozzle
@100 psi .0211 gpm per nozzle
Now using these figures lets say i used a setup of 10 nozzles. I hook up my pump and run it. How would i really now what my systems true psi is. How would i know what my real flow rate was? Wouldnt i need some sort of regulator. Obviously the more noozles you add the lower the pressure drops and vice versa. How do i fig out how many nozzles i can use for a specific pump
thanks alot john that really helps. I still am slightly confused on what i would use as a cycle timer, is there any way you could post a link or maybe a picture. An example of how all these components assemble would be awesome.
