Hi guys, I'm a total novice with PCs so please treat me like one. Assume I know nothing (and you won't be far wrong).
Approximate Purchase Date: Within the next month or 2
Budget Range: £1300 - £1500 (Current build is approx £1390)
System Usage from Most to Least Important: Gaming on the best settings hopefully for a few years to come, more gaming.
Parts Not Required: n/a - I need EVERYTHING
Preferred Website(s) for Parts: Ebuyer.com dabs.com
Parts Preferences: Intel, Asus, Coolermaster, Corsair
Overclocking: Maybe in the future when I understand what it is and have decided if it's worth it or not
SLI or Crossfire: Ditto
Monitor Resolution: 1980x1080
Additional Comments: What I mostly want to know is:
1. Do I need to buy anything else to have a fully-functioning PC? Cables, parts, etc.
2. Is everything I've chosen compatible?
3. Is the build reasonably balanced?
OK here's my build:

Although I think you should try and cut costs i.e.
smaller hard drive,
borrow a friend's windows 7 disc or torrent it from the piratebay,
a cheaper motherboard at half that price,
not buying an SSD, certainly not an SSD at 120GB (and I don't think the quicker load times are worth the price)
Not buying a gaming keyboard because to me that just seems silly
Only having 4GB of ram - enough for games
An 800W PSU is Overkill
First off, don't pirate windows. And to the poster above, please do not promote that behavior here, it isn't appropriate.
Secondly, your build is fine.
Keep the SSD. 120GB is the sweet spot and it does make a difference. Not in gaming, but for the speed of your PC. I would suggest a different brand like Crucial or a Mushkin Enhanced.
Getting a smaller HDD is silly. You aren't going to pay 1/3 of the cost for 1/3 of the space, so you won't really save much money but will lose a lot of room.
Get whatever KB you like, I don't see the need in it but some people like them.
Get 8GB of ram, it's not that much more expensive.
You could come down on the PSU a little if you want. If you aren't ever going to Crossfire you could come down to a 550-600W PSU. If you plan to possibly Crossfire like your OP stated, you will need 750-800W.
You definitely could save on that mobo. You could get an Asrock extreme4 for way less and still have almost the same exact features.
Lastly, don't waste the money on a sound card unless you have some elaborate surround sound system, the sound on the mobo is very good.
To your questions:
1. You shouldn't need any additional cables. Your mobo comes with SATA cables and the PSU has everything else.
