If I bought a rental property in March, can I claim full depreciation for the entire year?
Do I have to prorate depreciation based on the months I actually owned the rental property? (9 out of 12 months). Is bonus depreciation a factor in this at all?

No, you can't. The month you bought it is not used to compute depreciation unless it was the same month you offered it for rent. Depreciation starts the month you offered it for rent, and for that month, you only get half a month's depreciation.
