How to use SVN and Eclipse in a workspace together?

I wrote a simple Android application, but now I want to add it to version control.

So, I installed Subclipse, but there are two problems:

• My project is in [workspace] / MyApp, but I want to move it to [workspace] / MyApp / work / trunk (where work is the SVN working directory)

  I always get an error that I should not overlap the workspace. I created another workspace and used it with this project - but is this really the best solution?

• How about branching? I came from Code :: Blocks, where you can just move the project file! I think in Eclipse it is a little more complicated. Is a refactoring / copy solution available?
