When I go to pull my primary off with a clutch puller do I have to worry about alignment of the clutch when it his back on or will come off the same way it came on? Little worried this will offset my clutch when I go to put it back on the jack shaft. Any tips/help on this would be greatly appricated!!

Your primary goes on your crank not your jackshaft... and yes your alignment will be off.

If you are taking your clutch off, and putting your clutch back on, there should be minimal change in your primary to secondary clutch alignment, especially if the sled is new.
The sled is used some, and if you clean the taper of your crankshaft, or the taper on the clutch there may be a slight difference in where the clutch comes to rest when pressed on the the taper using your primary clutch bolt. (DO NOT OVER TORQUE!! 51 ft-lbs for Proclimb primary)
The clutch alignment tool (p/n 0644-428, 12.1" center to center with 1.485" offset) is a quick and easy way of checking your alignment, and, as mur190 pointed out, they're pretty cheap. I replaced one I lost this year and it was $28 from my dealer in Grande Prairie.
If you can't get to a dealer to buy the alignment bar, there's a little work around you can use, provided you own or have access to a decent quality caliper.
Mark the numbers 1, 2, 3, and 4 on the thin flat section of your stationary sheave at 12:00, 3:00, 6:00 and 9:00. Basically your 1/4-ing your clutch off. Then, measure the gap from the backing plate on the stationary sheave to the torque bar and record the four measurements. Once you put your primary back on, measure at the 4 points once more and compare them to your first set of measurements. They should be pretty close, and if they are off by a few thou (.001"-.005") you're golden. I think max gap allowable using the alignment bar is .030" so a few thou either way isn't gonna hurt much. (Can someone confirm that .030" max spacing? I can't remember if thats 100%)
This being said, if your clutches were not in alignment in the first place, they aren't going to be in alignment now. The Cat service manual states that offset must be checked whenever the drive or driven clutch is serviced. And further to that, even if your sled is new, they may not be in alignment. It may have been missed, looked over, measured incorrectly or measured very close to the max allowable tolerance during the PDI.
But.... If you don't have the tool, this should get you by. But then as soon as you can, check it with an alignment bar.
