Huge question! so many answers..
a very simple newbie DSLR site:

There's LOADS more stuff like this on the net, a quick google search will probably give you more info than you can possibly read.
However:
www.dpreview.com is probably the best internet forum, loads of constructive people there for when you have queries in general or about your specific model
Lots of the monthly camera mags like 'digital camera' and 'digital photo' include basic tutorials either in print or usefully on CD, with examples and guides and specifically on photoshop - find one you like the style of and start working your way through the tutorials, they're often loads simpler than they look.
Photoshop is worth persevering with - there is SO much support / tutorials / addins etc, its a great tool and the right tool for the job.. many cheaper alternatives, and while theres an argument that says the right tool is the one you know how to use, I would say if you already have this then its the one to put the effort into!
Many of the photoshop books available come with tutorial CDs too - have a look on ebay..
Here's a site with a bunch - again, there's loads more out there!

Have fun - thats important - take lots of pics, work out what you like and dislike about them, and then address those aspects - dont be dictated to by others about what makes a good picture, if you like it then its good - a lot of traditional photography 'rules' are being rewritten nowadays, and thats no bad thing!
Feel free to PM with specifics - I have a couple of DSLRs, (not your make though) and a son doing Photography at college, also with a bunch of this kit.
