Not sure if this helps... as i cut my teeth on PS (started with photoshop 2.5, still have the discs...) and i've only used the demo of PSP (kinda "flip" of you) but i've found it not to difficult to make the transition. most of whatever you want to do will be "somewhat" intuitive (based on your skill-set with PSP) with some "retraining" of thought.  

Keeping in mind, there are ALWAYS any number of ways to accomplish the same results, it's up to you to decide which is the best method for you. Some methods seem complex but offer a way out if you don't like the result (without resorting to REVERT), other methods are "quick and dirty".

The real learning curve is when you want to push the envelope, but that's what we're here for! feel free to ask a "How the 'L do you do this!!!" question, cause opinions and suggestions are like rectums, EVERYBODY has one!

 

remember we're here 24hours-a-day 7days-a-week (just not always in a row)
