Replying to First desktop build help

So I am about to order parts for my first computer build, but I really don't know anyone who is knowledgeable with computer hardware and I only have a basic understanding at best. This is where you guys come in, can anyone with computer knowledge confirm that my computer will function?

My (potential) build:

Corsair Obsidian 650D case http://www.newegg.ca/Product/Product.aspx?Item=N82E16811139006

Asus 23.6" monitor http://www.newegg.ca/Product/Product.aspx?Item=N82E16824236052

Western Digital Caviar Black 1TB HD http://204.14.213.175/Product/Product.aspx?Item=N82E16822136533

Asus Radeon HD 7870 2GB video card http://204.14.213.175/Product/Product.aspx?Item=N82E16814121649

Antec High Current Pro 750W PSU http://www.newegg.ca/Product/Product.aspx?Item=N82E16817371052

Corsair Vengeance 8GB (2x4) DDR3 RAM http://www.newegg.ca/Product/Product.aspx?Item=N82E16820233185

Asus Z77 Deluxe Mobo http://www.newegg.ca/Product/Product.aspx?Item=N82E16813131818

Intel Core i7-3770s CPU http://www.newegg.ca/Product/Product.aspx?Item=N82E16819116503

Corsair H60 Liquid CPU Cooler http://www.newegg.ca/Product/Product.aspx?Item=N82E16835181015

Asus Blu-ray burner http://www.newegg.ca/Product/Product.aspx?Item=N82E16827135252

Any pointers/advice on what to buy or how to save money are welcome, however the money isn't a huge deal.
Also:
1. Is my PSU a proper wattage? Should I go higher or lower?
2. Do I need to purchase thermal paste extra? Or does intel supply it with the CPU?

Any help would be greatly appreciated! :)
