I think a mechanical keyboard makes perfect sense for you. You spend a lot of time on the keyboard, so you deserve a comfortable one.
I think your safest bet is a TenKeyLess:
- Filco Majestouch-2 TKL (black or white)
- RealForce 87UW (white)
- RealForce 87UB (black on black - warning: the keycaps are unreadable).
The Filco will allow you to change the keycaps (it has Cherry MX switches), but the RealForce is generally considered as more comfortable thanks to the Topre switches.
A good near-60% Topre board I would also recommend is the Leopold FC660C. Its layout is not too far from the compact aluminum Apple keyboard.
As you seem to be in the UK, the best provider for you is the Keyboard Company. For me, they have a perfect record of fast delivery and perfect quality on the 4 orders I have made in the last months. So I have no problem to recommend them warmly.

http://elitekeyboards.com/products.php?sub=leopold,compact&pid=fc660cThe FC660C uses Topre switches, so be aware that it's not easy to find replacement keycaps. However I can tell you it's one of the best 60% keyboards available at this time.
None of these are Bluetooth, and they do not provide a USB hub.
If you are a little bit more adventurous, it looks like the Keyboard Company is going to receive a
Bluetooth 60% board, the Filco Minila Air:

Good luck and welcome to the community of mechanical keyboards users!
