Different people find it easier to get up to speed in different ways,
and you'll probably find that some bugs and features are easier to
tackle with one approach or another. Your best bet is to experiment and
find what works for you. Don't be afraid to change your approach if one
isn't working for you.

For bug fixes and small features (like improving a warning in clang,
say) you probably don't need to worry too much. Just dive in, and in the
worst case someone will manage to fix it before you do - that's fine,
you'll still learn something and that'll probably make the next task you
try easier.

This largely depends on the size of the change. You should aim for small
changes at first, and for small things just sharing the final patch
generally makes sense. That said, feel free to ask for help if you need
it before you've managed to complete the patch. This list is a good
place for that, as well as the #llvm channel on irc.oftc.net.
