I too am new to the tinkilt love. A friend told me to read Momento (http://www.digitalcandy.net/users/shaenie/momento.html) by shaenie. It totally broke me, as did the rest of the stories in that series. You may also want to read ukcalico's stuff (http://www.yearningvoid.net/calico/#lotrrps) especially sabotage (http://www.yearningvoid.net/calico/sabotage2.html) and it's companion subversion (http://www.yearningvoid.net/calico/subversion.html). Again with the breaking.

Also, esorlehcar wrote some recs and squee (http://www.livejournal.com/users/esorlehcar/71017.html) which was good times. Oh right, and of course image_direct for more pictures than you can squee at.
