You probably don't need anything else as far as parts except the new jets, but it would be smart to have the A/F checked on a dyno to ensure the proper ratio. I beleive 150 is pretty close to max for a stock fuel pump.

The stock fuel pump may not be able to supply enough fuel once you bump up the nitrous past 100 wet.

I've been running a 225 shot on my stock 97 fuel pump for quite a while.
I've pushed it though... im sure. I see 0 problems with a 150 shot on stock pump as long as you are not running aftermarket cam and heads with a high redline ( rpm's ).
