Hey guys!! The snake is running boggish lately... isnt picking up speed as quick as it used to... and as soon as i hit the gas on any gear... it hesitates a little

figured the car just needs a lil tune up so decided to change plugs and fuel filter (motocraft)... running a little bit better but not much... check engine light came on and had the car scanned... guy at the shop didnt tell me the code but said that the car has a bad MAF amongst other things as well.... where (online) can i get a good MAF and what kind??? as for 02 sensors.... what kind and where can i get them.... also... i dont have cats... so where and what kind of MIL should i get???? links would help out a lot guys... and any other suggestions on how to get this car running like it should?!??!
