First, you should identify what parts of your .emacs take so long. You
can do this e.g. by starting emacs with "emacs -q", set up your
load-path, and then evaluate
(benchmark-run
(require 'package))
The first number appearing in the echo area will be the time needed to
run that command.

Many packages from Emacs use autoloads, which delay the loading of the
complete package until one of the interactive functions is used.

Essentially, yes. But maybe you "require" too much. My emacs startup
time is ~1sec, although I include large third party packages like CEDET
and Gnus. For example, for setting up Gnus, you should only require
'gnus-load in your .emacs, which contains the proper autoloads. This
takes about 0.03 seconds on my machine.
If you want to set options which need to be evaluated after a package is
loaded, you can use eval-after-load.
