Help required to tweak Moon theme

[giokookie]

Some things that need to be done:

1) Get my logo to show.
2) Configure the PayPal API to work with prestashop. ( i have set it up but when i try to checkout with sandbox, it says "Authorisation to PayPal failed")
3) Shipping cost is wrong at checkout. figure and fix problem.
(for example, customer buys 1X product A & 1X B postage is $6.09. customer buy 1X product A & 2X product B, postage is $3.05)
4) remove paypal logo from footer
5) to get jqzoom to work. I have the fix but do not know where to place the code without messing up the product page.
6) to move customer loyalty block to below the add to cart in product page
7) to move product description under the add to cart button in product page
8) now when you go to the Categories page, the price, add to cart and view product options are under the product image where you can see it when you place the mouse over the image. I want to have a fixed product image with just a view and add to cart button under it.
9) At checkout page. to have a pop-up box confirming delete when cusomers click on X (delete) button.

this is my site (www.thegeishapearl.com/prestashop)

I don't have much budget for this job so if someone doesn't charging lower to tell me which file and where in the file to change things, I would be very grateful!
