PhotoImpact is an awesome program! Although I also use Photoshop CS, PI is my program of choice for designing elements. Much easier. It's also very easy to put layouts together in because you can open a window where your files are and then just drag them into PI to use. Drag a background in then drag and drop all your elements onto the background and they are automatically put on their own layer. EASY!
I learned how to use PI through the
PIRC Beginners Workshop which is free and totally self paced. You will learn your way around PI by doing hands on tuts and it's tons of fun. I highly recmommed it for newbies just getting their feet wet. Even those who have been using PI for a while can benefit from it greatly. There's so much that you can do in PI.
Also be sure and check out
PIRC (PhotImpact Resource Center) They are SOOO helpful in the forums there and you can get all kinds of free objects, presets, textures, more tuts and they even have a scrapbooking section on the board
