Theme development

I am reading the excellent explanation of forms api by merlinofchaos.
http://api.drupal.org/api/HEAD/file/developer/topics/forms_api.html

He has this example.

form['foo'] = array(
'#type' => 'textfield',
'#title' => t('bar'),
'#default_value' => $object['foo'],

What does the # sign mean? I can't find it in any of my php books. I looked under # and pound sign in the books and on Google.

Im using a simple tabbed list for navigation of primary links. Is there anyway to easily sense the current page and restyle that corresponding tab or will I need to hack the core and insert an id="current" or some such?

I'm fairly new to PHP but i'm starting to get the hang of it.

I'm creating a new login and i'm using this
print l($user->edit account,'user/'.$user->uid);
with the user name going to the account options

My question is how do I change the script to read out" Edit Account" instead of showing the user name?

Thanks,
Greg

Hello all!

An utter newbie at Drupal, I'm slowly getting along with my little site, but this thing is killing me! I'm trying to put together a CV-maker of sorts using a Flexinode node, where I want to display taxonomy terms as so (strong=taxo-terms):

Born in Happyville, 1978. Lives and works in Taxonomyhell, Norway.
Artistic expression: Sculpture, Installation and Video.

This is what I have in my node-flexinode-n.tpl.php file so far (it may be extra stoopid due to fatigue):
