I think I'm in that early stage where there are one or two key things I don't know. The alternative is that I'm hopeless. :)

Hehe in the early stages you probably won't even seeing the edges.  :)  I recommend reading all the documentation about Projects, Snippets and Language Grammars a few times, as well as installing the GetBundles bundle.  Also, press ctrl+opt+cmd+K to bring up a fat menu of keyboard shortcuts.  I'd also read the keyboard shortcut documentation because the shortcuts are somewhat organized according to their functions (for example, shift+ctrl+opt+<letter> type shortcuts are used to switch your current language.

And of course feel free to ask the list, people here are more than happy to answer.
