Convert a Template to a Website

Hello, I am moving my current website to a new template which I have on a test URL currently and you can find that URL in the attachment. I need to make sure this new template is W3C compliant and that it loads quickly (around 1.5 - 2 seconds) and is basically very "friendly" to search engines before I put it live. I want to be sure it can be completely spidered by the search engines. I'd also like if you could take a look at it's url structure and check for canonical URL's and dynamic URL's. I'd also like to be sure the page size is less then 500 MB's. Any other suggestions you might have to make the site clean coded, fast and search engine friendly. Thank you.
