Answers to two of your questions interspersed below. (Probably was a bad idea to ask so many questions all at once. Granularity is good!)

Move the cursor to the right of the current cell and you should see a cell bracket (in case it's not already there). If the cell bracket is actually enclosing a group of cells (or groups), it will have a small hook at its bottom. Select that cell bracket and double-click it.

You refer to "the tiny triangle to the left". By default, you would never see such a GroupOpener. Either your notebook is using a style sheet where the option ShowGroupOpener has been applied to the Section (or Subsection, etc.), cells involved, or else a GroupOpener was explicitly added to that Section  (or Subsection, etc.).


> 4. What are your tips and tricks for newbies learning how to do stuff in mathematica? For example, one trick I learned is to use the Cell->Show Expression hotkey (Shift+Ctrl+E) to steal low-level code of things I don't understand yet and paste them into other things and figure out what they do. I'm looking for more 'tricks'.

Take a look at the following post to mathematica.stackexchange.com:
