OSB works great in a garage. Not only is it more versatile, it's significantly cheaper as well.
Check how large your service is, and put as many receptacles as you can in there. Pretty easy and cheap to get a couple breakers and put some more outlets in, presuming you've got the capacity, and you'll never regret having too many receptacles. Last garage I built, I put (13) 120v outlets and (2) 240v outlets in.
Find an electrician to befriend. They're constantly replacing lights, and ever electrician I've ever met has had access to more spare fluorescent lights than they know what to do with. Once again, you won't ever think "Man, I just have too much light in here". Keep an eye out on kijiji and the like for ballasts too. They can get pricey to buy a bunch of them, but I've always been able to find someone with a bunch of them kicking around that they've just given me.
I have (3) 2'x4' and (3) 1'x4' lights in my current 22x22 garage, and with 11' ceilings, it's not overkill at all. I might actually replace the small ones to get a few more tubes up there.
I also ran a split receptacle out there when I was doing some other electrical in the house, so I've got 3 dedicated 120v/15amp circuits and a dedicated 240v/30amp circuit.
Don't have to spend a bunch of money, but a couple hundred bucks and some thriftiness and planning can make a huge difference.
