Recommendations needed for late 2006 iMac - Optimal Setup

In the last few months I have done a little updating of our old iMac to try to give it a bit of life and hopefully keep it going for quite a few more years. However, I am no expert and would really appreciate some experienced thoughts on what I can do with what I have to make it the best it can be. Right now its being used as the main source to sync all iPods, iPhones, iPads, for our family of 6. When its used, it isn't taxed. Internet searching, iPhoto, microsoft 2008 word, and iTunes are primarily used programs. I would ultimately like have it as the family "server", if I can even call it that. One location to store all of our photos, music, videos, etc. We also have an older macbook and a macbook pro I bought for the wife this past January.

Since this is only G wireless speed, I ordered a USB wifi adaptor to hopefully get free up the apple express it is ethernet cabled to currently to achieve N wireless speed. All the research I have done tells me I can't add anymore ram. Is this true? Since it has no bluetooth could I add it to the mac? I had read of CPU upgrades done, but don't know if its worth the hassle since the SSD I added was the best upgrade.

BTW I hope I have chosen the correct location for posting….. I appreciate all thoughts, just don't beat me up in the process!
