How About Some Website Advice?

[wiskic10_4]

For day four of Nihil's One Interesting Post a Day for 28 Days Challenge I've decided to ask for a little advice for my website.

Check it out: http://www.jeremydean.co.nr

I would like to know -

What can I do to improve the layout?

What do you think of using the .htaccess/.htpasswd system like I have setup in the downloads section? Secure?

How can I improve my Google ranking - I'd like to be in the top five when someone Googled for "Jeremy Dean" - is that setting the bar too high (with all of 55 hits in a month. :P)

Is there any simple code to enable users to add posts and upload files? I have WordPress installed, but I need to spend some time getting it configured.

What I'm wanting to do is to basically set-up a little private facebook-like site (based around me of course) and also provide a place for registered users to securely share files w/out having to worry about "the man" :P

What are your thoughts? Be critical - hell, be outright mean! But try to be helpful.

Thanks!
-jeremy

If you find any gaping holes in security, please PM me rather than posting here - shouldn't be any, but then what do I know?
