Fixed commuter disc brake stealth motherfucker

Hi all,

I'm after a new bike and after some consideration have decided to build one myself. I have never done this before and consider myself one of the world's most unpractical people (I know that's not a word but impractical makes me sound like I'm annoying to use on a day-to-day basis, which is not the case).

I want a fixed gear bike with a disc front brake. I would like the ability to have mudguards and possibly a rear rack. I also want the build to be as light as possible. I am overweight (around 80kg but am a tiny manlet) and realise the folly of this, but I just like the feel of a light bike and I have to lug it up and down stairs every day.

I'm thinking of the following:

Frame - Dolan FXE
Forks - Kinesis DC37
Front wheel - Hope Pro 2 Evo laced to H Plus Son Archetype
Rear wheel - surly ultra fixed laced to H Plus Son Archetype
Crankset - Miche Primato Advanced
Bottom bracket - HELP (what do I need?)
Sprocket - TBC
Chain - KMC Z510HZ
Headset - Alpina (included with frameset?)
Stem - Deda Zero 100mm
Handlebars - Cinelli Lola
Front brake - Avid Elixir 5
Seatpost - Alpina (included with frameset)
Saddle - Selle Italia SLR
Pedals - Shimano M780XT
Tyres - Michelin Pro 4 25mm

So far cost has come out to 1,074 but I still need the bottom bracket, inner tubes and bar tape. Weight is 7.2KG but I'm not sure whether the listed weight of the FXE frameset includes the seatpost, clamp and headset?

I basically need to know whether (a) this will work and (b) if you would upgrade / swap any of the components I've listed.

I also need some advice on which bottom bracket to go for... dunno what I need so far as chainline goes but I assume it's whatever will give me 42mm?

Can anyone also recommend a tool set as well?
