Definitely do the upgraded electrical now. If you ever want to do it later it will cost you a lot more. Also not a bad idea to slope the slab out towards the lane (I think it's a better option than a floor drain), in the winter you do pick up quite a bit of snow and junk on your vehichle and it's sometimes nice to be able to hose off the floor in the spring. I'm sure you don't need to be told this but make sure the apron outside slopes away from the garage, the moron who did the driveway at my house left a low spot and after heave rain I will get water seeping into the one corner of my garage. Given the size of the garage I think a standard door is 16x7 and that will be big enough. I mean it's not like it's a 30 x 30 shop with a 15 foot roof. I guess the only draw back is if you sell the place down the road and some guy has a superduty truck with a 33" lift kit won't like it.
