If you're willing to spend that much just go to Sony's website and choose the parts you want and have them put it in a laptop for you. You can't go wrong because they don't let you choose things that would not be compatible. I spent £1249 ($1892) on my laptop in the end. current specs are:

I didn't bother with an SSD because I wanted more space not faster access times. Also this is a Sony Vaio S series, if you go for the Z (Sony's best of the best) you end up paying at least 1.5 times more just for the "Z" I think it also comes with an SSD and a HDD but for and extra £400 it wasn't worth it when the CPU, GPU and motherboard are still all the same as you get in the S series.
Also this laptop plays games like Fallout 3/NV on max settings without lag. I don't game much but it's nice to have that functionality.
To summarise your points in comparison to my laptop:
- quad-core (or more! Though I doubt the possibility, at least in my price range...)
Mines' Dual core 4 threads, so shows up in task manager like a quad core would
- processor reaching near or (preferably) beyond 3.0GHz
2.5GHz here
- backlit keyboard (night-time work is probable)
Check comes standard I believe, don't think I paid extra
- preferred 15" or greater screen size (flexible, and not priority)
I think my screen is 15" certainly greater than 13 though
- USB 3.0
2 usb 3.0 ports 1 usb 2.0
- ram 8gb or greater
I paid for 8 you can get up to 16GB if you want but I don't really see the point.
..
- 802.11n (and maybe one with those fancy new 802.11ac models... not necessary though)
Laptop comes with Wireless LAN support, you can also pay extra for WLAN
- disc-drive
Yes, which also doubles as a bluray drive if you pay extra. I did, there's no point buying DVD's anymore.
- HDMI-out port
Yes
- good battery life
Depends, I payed extra for the attachable sheet battery which takes the battery life up to like 8 hours without that you'll get 2 hours as best
- good graphics card (I don't know much about graphics cards, so help there is appreciated)
You have 2 GPU's to choose from I went for the more up market one
Desired, but not required:
- bluetooth
I'm pretty sure this has bluetooth though I don't use it
- slot load disc-drive as compared to tray-load
Yes that's default
- blu-ray reader/writer
Optinal, see disk drive
- Full HD 1080p screen (I'll go out on a limb and say "3D!". I wonder, does touch-screen 3D work?)
Yes, also has some kind of 3D function I believe but I'm not sure what the fuck it is
- Full HD webcam - whatever that means. Can't imagine it going beyond 2-4 MP
No idea what quality the webcame is, I don't think it's HD though. Personally I would have chose not to have a webcam if I could
- 0.2 pounds in weight. Yes, I'm joking
The laptop is incredibly light without the sheet battery, with... not so much
