Driving me crazy - Two missing fics

[emn1936.livejournal.com]

I cannot remember the titles (or authors) of two stories, the plots of which simply won't leave me alone.  One of them is a story I sought out quite some time ago, got the title, and have since lost the link so here I am, try, trying again.

First story:  Kirk and some of the crew are trapped on a planet and Kirk has to fight - gladiator style - to save them all.

Second story:  Kirk's got a thing for Uhura but she's going through a brutal breakup with Spock, has revenge sex with Kirk (I think) but eventually they end up together - after an accident in which Spock is injured she realizes her true feelings lie with Kirk (and they have a tender, funny moment where he tells her that there's a whole world with just the two of them, something like "Sheetalus" and there are only a few words in the language of that world.

Anyone?   I'd sure appreciate it so I could stop trying to remember!  Thanks much.
