What buttons do I press?

[TeddyGirl]

OK gang....it's gone past midnight....I started tackling these problems 10 hours ago and I haven't moved from problem 1.

Please can someone tell me what to do with the following:

• How can I get my products list to look like the one on either this site: http://www.chilternmills.co.uk/cat/b...s/default.aspx or this site: http://www.zen-cart.net/demo/index.p...products_id=34 - I've tried changing all sorts of values on Admin, but it just doesn;t seem to come out as I want it.
• When you select a product on the 1st sites page, it takes you to another page and gives you an option to pick a colour from a list of radio buttons (this bit I can do). When you select a colour, the image changes colour too - how can I do that?
• How do I "switch on" the "Also purchased box"? Again, I've tried tweaking with various options in admin but it just wont appear!!!

Somebody please help before I go completely mad!!! It's probably obvious and it's probably staring me right in the face but I'm just so brain dead I cant seem to see it!!!
