You're going to have to help yourself a little here...
1. LOSE the buy now on the category pages. Your products require options, so in your general settings>appearance, DISABLE: Enable "Buy Now" button in the products list:
AND -- in Product options options
A customer using the "Buy now" button to order a product with product options must be redirected to the product details: CHECK THIS BOX
2. Get familiar with the admin-- learn how to determine product ID (I gave it to you a few posts back)
3. Your header image is in serious need of repair... do you sell web design services? You are going to have difficulty getting clients with a logo that looks like that.
4. Your color palate...
The way this cart works: you're going to have to start flipping switches to see what happens... There is a steep learning curve on many levels.
Good luck.
