The pipes going into the cats are for the air thermactor system. Leaving them off won't affect it much, othe than exhaust will leak out of them if they are not plugged up or the pipes aren't installed again. You mean the throttle sticks? Does the pedal depress alright? Does it feel like there is some resistance? Check to make sure the linkage for the choke isn't binding or anything. These cars aren't going to be really responsive when you first start them up, they have to warm up. My car did the same thing, if you revved it when then engine wasn't warmed up it would bog and everything else.
