Java Environment Help

Hello everyone, not sure if this is the correct forum to post this in but here's a shot.

I know C# very well but only dabble in java, I know in order to mod anything in tekkit I need to download the correct builds and dependencies but have never used Git before. I'm a subversion fanatic. Is there anyone out there that can point me to some good instructions on how to get my ecclipse setup so I may start modding the various plugins in tekkit? Is there a jenkins where the compilation of tekkit code is available or do i need to download the various plugins that consist of tekkit from their respective websites, find the right code version, etc. Sorry theres just so much information and I do not know where to start. Once I find all my dependancies though I would love to assist people on this forum with simple bug fixes! Help a noob dev out? Thanks guys!
