Take it as directed by your physician.
If you are ever in doubt you can always check with a pharmacist.
Absolutely, from, a toxicity standpoint. Many patients are on 1000 mg of metformin twice a day. On the other hand, if you are new to metformin, watch yourself if driving, and you might want to check your glucose levels an hour after the dose.
