Hello Nikiforos. Welcome to PSG.
It would help as peta said to see some of the images you are having problems with.
What kind of albums are they? Family & friend pictures? Shots for clients? Knowing that might help to advise you on how to "spice them up." Just remember, the largest part of the work should be done in the camera. Definitely, given your problems, open them up in Camera Raw and go through the basic and detail steps.
In Photoshop, go to File>Browse in Bridge. Find the file you want to work with, highlight it, then choose the icon second from the right, hover and it says open in camera raw. Once opened, you will see a histogram at the top right. Underneath is a line of icons. The first from the left is basic and the third is detail. Also, on either side of the histogram you will see triangles which are dark and light clipping warnings. Click these and when you play with brightening, if you go too far, or if there are too many highlights to begin with, you can change exposure or use the recovery slider, etc., and watch the red go away; likewise for shadows which turn blue when all detail is lost.
I can't give you any more guidance with camera raw unless it is a specific question; there's too much to explain in a couple paragraphs. It's not complicated but it helps to get a guided tour through it or at least learn what each of the features are.
So, give us a bit more to work with and we'll give you the best advice we've got.
