You have different options for a dock it's merely a matter of installing:
- there's 'plank' which I prefer to 'cairo-dock'.
- And there's 'tint2' that is very usable.
All docks have their pros and cons, it's a matter of taste.
I wrote a Howto on customizing E16 and both docks as well, here:

You might want to explicate that and it could be interesting for us too.
BTW: I would advise to editing your previous message and remove the e-mail address .... it might be 'harvested' by spambots. 
By DM I meant via this forum.
The installer asks if you would like to send/participate and subsequently asks for an e-mail address.
You might've missed that.
