Grouping related buffers

You might want to try "eproject".

It doesn't exactly group buffers, but it stores workspaces and allows
to switch from one to another quickly.

With eproject, a workspace includes a set of files and their positioning
in the editor, a separate menu that shows only these files (i.e. not mixed
with nonfile-buffers), and another menu with custom commands (typically make
commands) which can be optionally bound to shortcut keys.

Another feature is that when you close emacs it remembers the current
project and reopens it automatically when you start emacs the other day.

Basically it implements some of the behavior that is known from common IDEs.

As to working on two projects at the same time, I'd just open two instances
of emacs.
