Calcium: Not much to choose from. Go to the drug store and look at the several options for calcium. Carefully read the comments on each one and choose the one you think is best for you. Try focusing on the less expensive end.

No: No, the only difference is that the former is better taken with food whereas the latter (calcium citrate) can be taken on an empty stomach.

Either: Just make sure you take the proper amount to balance with your diet and take 2000 units vitamin d3 as well, citrate is easier to absorb and doesn't need to be taken with meals, but can be more expensive and less "calcium dense" per pill.
