Now do I use the rebuilt library the same as I would the original iphoto library?
yes
Could I reload iphoto with my disk? and delete the old one?
Sure you could - but it will probably not help and is much more likely to cause additional problems - It is ill advised unless we test and determine that the problem is the iPhtoo Application - which has not been done and again is very unlikely
If you really want to go that way the first test is to launch iPhoto while depressing the option key and creatting a new library and irting a few photos - if that works (which is likely) then the iPhtoo Applications is not the problem
If that fails then you do the same test in a different account - if that works then iPhtoo is fine - if it fails too then there is a problem with yoru account and it coud be preferences, the OS or the iPhtoo Application and additional testing is required
But the overwhelmingly likely case it that your library is corrupted and needs repair
