So much info! I will definitely check all the things you awesome people have mentioned above. Yes, the rims are 27x1 1/4 but I think a place called CyclArt, here in Southern California, can adjust the rear hub spacing to fit the 700c wheels. I was also thinking of doing a fixed gear conversion. Thanks again for all your help and advice!

Right ON! I just found that sticker taped underneath the bottom bracket area that says PH10S and some other numbers on top. Sorry for all the trouble! T_T
