I am currently using Unity, and finding it on the whole very good. However, the Dash is not particularly useful to me, and I would like to set the default action on pressing the BFB (is it still called that?) to opening the docs lens, as that is generally the most useful one to me.

The problem could be in corrupted FTS index. See the bug report.
The solution is to remove the index - this shouldn't affect your overall history of activities.
zeitgeist-daemon --quit
rm -rvf ~/.local/share/zeitgeist/fts.index/
zeitgeist-daemon --replace
(Based on Michal Hruby's solution from the linked bug report.)

It is configurable. The unity icons are in /usr/share/unity/4. Please browse this folder with the file manager to see the thumbnails.
Here is an example to change the look of the default dash home:
cd /usr/share/unity/4
sudo mv squircle_base_54.png squircle_base_54.png.orig
sudo mv squircle_shine_54.png squircle_shine_54.png.orig
sudo cp round_outline_54x54.png squircle_base_54.png
sudo cp round_shine_54x54.png squircle_shine_54.png
Log out and log back in. You will see the new dash home.
Definitely more customization could be done as long as you replace the correct files. Please backup the original files before making the changes.
BTW, maybe you have the question: how do you know the solution? I hit the same problem and tried to search all related files:
sudo find / -type f -iname "*dash*"

This is currently not possible, however you can use the Super-F keyboard shortcut to open it directly.
In 12.04 the plan is to just let you drag the lens from the dash and put it in your panel, but this isn't implemented yet.
