Love it! What gear ratio are you running? Are you planning on racing it?
As to the disc brake question, disc brakes were banned in UCI categorised races up until last summer. For most people this had no impact as the vast majority of cross races in the UK are not UCI categorised, but it did mean the pros couldn't use discs. In my experience, road shift levers and mechanical disc brakes don't mix well so braking is nowhere near as good as hydraulic discs. With the rule changed I'd expect someone to bring out hydraulic discs that work with road shift levers in the next 12 months.
