jay322,
welcome to
RP.
the best way to learn is to figure out what you really want to do. 'photoshop skills' is a pretty generic category. you need something more definite. one of the things i found is that there is a LOT to learn here and all sorts of different classes of 'photo manipulation'. you've got retouching, restoration, photo art, photo manipulation, fashion/glamour, pagentry, and even divisions within some of those areas and probably a few areas i didnt even mention. each has its own quirks and techniques and specialties. retouching is quite different, for example, than restoration. glamour is a real tricky one, with some of most fussy, finicky people in the business.
if retouching is your passion, find some images you want to work with and jump right in. there's no better way than to just start. do what you can and then find tutorials, books, forums and the like that can help take you further.
RP is an excellent forum site. we've got folks from all the trades in varying skills and abilities who are quite willing to help and answer questions.
i'll also mention that photoshop isnt necessarily the best program to start out with. whereas it's easy to say it's the best graphic editor out there, it's not the easiest learning curve. but, because it's the best, you're also going to find the most help for it. so, it's a bit of a toss-up as to where to start re graphic editors.
one shld also be familiar with the 'frustration factor'. this can range from calming, soothing, relaxing painting to exploding heads, broken keyboards and bouts of drunkenness and deep depression

i hit the high end of this fairly often and after banging my head on the wall for a half hour, i usually go back to before i got in trouble and figure out what it was that was perplexing me and start again from there after figuring it out. i'm currently working on a program that is quite complex and has little, good documentation. what docs there are spread out across many sites. so, half my time is spent just trying to find the tut i need and the other half in trying to understand it. (doc writers, in my experience, fall into one of two categories; either they are folks who already know everything about the program and forget that we dont, or, are folks that dont want to write things up and just throw some stuff in there to satisfy their bosses' orders to 'make some docs').
so, the last bit of advice i can give is, learn your tools and learn them so well that you could do this stuff in your sleep. if you know the tools, technique is secondary. you just KNOW what to do and do it because you KNOW what the tools can do. it's like the difference between a chef that has to read each recipe to get a good result and the chef that knows his tools so well that he just goes, ok, a pinch of this and a dash of that and voila'!
