Magento site changes

1 – Filter: I’ve put a multiple select attribute in my products which I would like displayed as a filter with colour swatches. Right now it seems to appear but when you click on one it just zaps you back to the front page. You will find this filter at the top of any catalog page Blues(181) Brown and Neutral(153) Greens(162) Hot Pink(2) Multicolour(28) Pinks(176) Purple and Lilac(131) Red(2) Reds(132) Silver and Monochrome(90) White and Ivory(158) Yellow and Orange 2 – Shipping I want to have a per-item shipping setup which works the same way as it does in Ebay. Every one of my items already has attributes for: Postage cost for first item. Postage cost for additional item. So if the first was £3, and the second was set to £0.20, then if a customer purchased 4 the cost would be 3+0.2+0.2+0.2 = £3.60. Now since this attribute is different in all my products and it is present in all of them, I would like it to at checkout add up the shipping accordingly. Now some items costs will be different, in which case I would want the checkout to take the highest first item cost and then add on any extra items. So say there was another product which had postage price of £1 with £0.10 for additional. If customer purchased only 3 of this item alone, it would be £1+0.1+0.1. However if the customer from the first example added 3 of these items into that basket then it would be the highest product plus the additionals making the total cost of the 7 items 3+0.2+0.2+0.2+0.1+0.1+0.1 3 – Name change I’ve decided to change the name of the new website which is being launched. The new logo is a purple/pink colour so I would like the colouring of the site to be changed to match the new logo. 4 - Slow loading I think the site is fast but when you click on an item which has a lot of colour variations such as: [login to view URL] You will see it loads very slowly. I think it is loading all the images in the background before it loads the page up so we need to work on priority I think. Also I find that if I’m scrolling and I click a product to open it in a new window, the original page wont continue to load until one has loaded up completely. If you've actually read this whole project, please start your proposal with the word coconut or I not bother contacting you.
