Changing water pump questions.
My question is which pump do I buy?

When I look up the part on various retail websites such as RockAuto.com, they list 2 different pumps for the same year... one has 2 hose fitting and the other has 3 hose fittings. So I'm not sure which one I need. Any suggestions?
Pumps should come with the gaskets correct? I don't need to buy gaskets separately, correct?
Just wondering what else you all recommend changing out at the same time.
Such as tension pulley, idle pulley, serpentine belt, thermostat, radiator hoses, and MB coolant.
Thanks
thanksanyone have answers to what other things I should replace while replacing water pump?
