Opinions will vary, but my advice is to use your distribution's package
manager where possible, and where not possible, file bug reports to
get packages added. I filed a bug report requesting weighted-regexp,
and a package was uploaded to Debian unstable less than 24 hours later.
Debian has a very responsive haskell maintainence team whose main issue
is identifying remaining good packages in hackage that have not gotten
I use cabal if I'm not on a development machine (so Debian stable rather
than unstable), and need a newer version of something.
The way Debian packages haskell packages lets cabal know about them,
so it interoperates nicely.

To find what package contains a module I typically use Hayoo.
From hackage to debian package name there is a simple transformation
before ghc7, use libghc6-<hackagename>-dev
ghc7 and above, use libghc-<hackagename>-dev

Opinions will probably vary, I don't like installing system wide
software outside the control of my distribution's package manager and
so have only used cabal inside HOME.
