Crack on with what you've got. i've got MTB (slim road like shoes) and Road shoes and just MTB (SPuDs) pedals. i bought a little convertor thing off wiggle so i could put MTB cleats on my road shoes. my MTB and Road shoes are made by the same manufacturer and the only difference is the tread on the bottom, you can't really tell the difference at a quick glance. they are as stiff as each other.
some people say you get more surface area with the road pedal (rather than MTB pedal) but i've never found this a problem. the shoe is stiff so you don't feel anything through the bottom! i dunno what the hell they are talking about. also, on my trip to paris, every day the ones with road shoes were complaining their feet hurt. mine didn't.
if you're feet are cold, try neoprene over shoes rather than two layers of socks. much better.
