Here are some links to sites which I'd highly recommend:

Games: 

AGS (Adventure Game Studio) the home of the excellent program with which I made my games:

TFGamessite A forum for makers and players of homemade games featuring transformations often of a TG and or sexual nature. 

TG:

FictionMania A huge and brilliant site full of captioned images and TG fiction.

TGStorytime Another great TG Fiction site. Newer and fresher perhaps that Fictionmania. 

Eunuch Archive A hub for the eunuch community and for writers of castration erotica.  

Rachel's Haven A forum supporting Transgender individuals, more aimed towards the fantasy side of life with captioned images, role playing and fiction.
