My experience is the with the Auqa C and it has been a great skimmer. The CPR is also a good one, just requires a little more maintenance. Depending on what you are planning on putting in the tank you really will not need a skimmer for at least a month or two so you would be better off saving and getting a better one.
As far as the books go, there are many great books in regards to SW
aquariums. All of them will have some of the same info, and some different. Fenner is just kinda the guru for SW
aquarist. All of the info is in one book, and is known to be true. As far as the lighting goes, it all depends what you want to do with your tank. If you just intend to put a few "nemos" in, those lights will work fine. If you think you will want some corals or anemones down the road you will prob have to rethink your lighting.
I would read up about cycling of the tank also. Getting the salt right is only a small part of the equation. You need to keep testing your tank to see when it has finished cycling. There are many different methods for cycling tanks, use which ever one you prefer. But, to avoid problems down the road I would prob slow down and do a little reading to save yourself alot of expense in the future.
