in my opinion, YES!!! i just finished up my new 30'x40' shop this winter. i don't know that you need 2 drains for each bay (i put one in each of my 2 bays), but that's your call. i did all my own carpentry, wiring, and plumbing work, but i hired a crew to do the concrete. if you're doing a shop with 4 bays, that's a lot of square feet to stay ahead of, in terms of concrete setting up, even if you do it in 2 pours, but you don't get any second chances to screed or trowel it. there's nothing more maddening than a concrete floor that has low spots creating water puddles, or a floor that won't clean up. i've run a few power trowels in the past, and it isn't something that you can just grab and go with. it takes a little practice to learn, and you don't want to mess up your own floor, because you'll have to work on it and look at it for a long time. if it were me, i'd spend a little cash and get a professional crew to do the 'crete work. i would (and did) have my concrete trowelled to a glass finish, and spray a commercial concrete sealer on it right away. you won't regret it. my floor cleans up nicely and easily. i was also cautioned by my 'crete contractor about a glass finish and it being slippery (living in n. iowa and snow, etc), but i haven't slipped yet. i had to "wrestle" him into it, but finally got what i wanted, and love it! the sealer helps with oil dripping, also- it doesn't stain the 'crete before i can throw some floor-dri on it. my opinion and my own experience, for what it's worth.
