What have been your next step after your first Installation ...

I really don't have any order, but my priorities normally include:

Restricted extras
Package update
Set static IP

For my server/MythTV box:
Configure MythTV (this takes me a long time)
Set up shares
Minecraft server
SSH

For desktop:
GPU drivers
Xmarks
Wine PPA
Coolkey
Oracle Java (it is needed for certain things)
Second browser (Firefox and Chrome)
Mangler
Configure Ubuntu One
Add server to FSTAB

1. Run the update manger and install updates.
2. Install programs/media plug-ins.
3. Install Themes.
4. Clean up via the terminal or Bleachbit.
5. Download/sync all documents/wallpapers from Ubuntu One that are carried from release to release but this was not applicable to my first installation.
