Hi nymonilc and welcome to the world of photo!
Photoshop does have a steep learning curve but persevere and you'll be fine.
Regarding cameras, it primarily depends on what feels good in your hand and while carrying. Cameras have to be used and you don't want to get stuck with one that you won't want to tote around with you.
I've used the Fuji Digital SLR, Nikon, Contax, and finally decided on the Canon EOS system. I like the way it feels in my hand and the quality of the images it takes. Go to a store and try them out and also try NOT to be persuaded by all the marketing hype. There have been some small point and shoots that have created beautiful images because the photographer knew what and how to shoot it.
Whichever system you go with remember 1 very important point: GET THE BEST QUALITY GLASS YOU CAN AFFORD!
Some people are tempted to go with multiple cheap lenses but you really will see a difference with high quality (Canon calls them "L" series and Nikon calls them "ED") You'll be happy with good glass for a long time and they tend to hold their resale value if you should ever decide to sell them.
Congrats again and welcome.
