Go to other worlds now. 2-1 should be your next bet. Equipment and stats are totally dependent on your class. There's a lot of solid TK builds, I've never used a Temple Knight, but things to think about when building your stats is what sort of play style you want and to make a good build an idea of what future weapons you want to use is good too.
If I was using a TK I'd focus on a faith build - easy to use (no reliance on enchantments and stuff to be awesome), high vit, end, and faith with just the base magic and strength needed for some decent weapons, ~18 strength, and 18 int so you get 3 spell slots and can use some decent weapons like great axe, large sword of moonlight, and blessed + 5's.
Basically Vit and End are the key stats then just choose which way you want to go with your offensive stat and gouge the fuck out of it, don't mess around just focus on a key thing like Strength, Magic, Faith or Dex, stats like int shouldn't be taken past 18 (at which point you get 3 spell slots) unless you're a magic build or require more than 3 spell slots for some reason. At SL 120 you wanna have something like 50 vit, 40 end, 40 something else. with everything else being just enough to get you through. You can make an all rounder if you want but it takes longer and you'll need to level higher/grind more to be effective. The advantages of levelling stats past 50 is questionable, basically the level bonus you get becomes more and more irrelevant past 50.
