Are you planning on changing a little thing, or a whole new design? I would advice a light, clean look, with emphisis on user accessibility. Meaning its clear, precise, and easy to move about on. ColourLovers.com - Have a look here for some colour inspiration!
That would vary. If you jstu wanted a coded design that you could add your links and pages onto, without any help from me, i'd do a Design, coded in XHTML/CSS with PHP Includes, for around £40 Usually, If I have to code any scripts etc, or make the actual site with content, it can go form £220 to well in excess of £800

Slightly off topic, but Man! You can get alot better hosts that T35. I was on there about a year and half ago. If you look around, you can get quality hosting free. I just found T35 so resticting. It may have chnged since then I really need to get a new portfolio up!
