If by output cap you mean the cap across the load, then no. It just filters the output.
If you're talking about the LM3410 output cap, then yes, it is extremelly important. It's pretty much the main cap on there.
The Fb voltage should never change. It should always be 0.191-0.193, depending on the IC. If it was less than this, the IC could be struggling, but if it's more, then you're doing something wrong..
It shouldn't really be 300mV.. Which version of the circuit did you make, anyway?
If you make some pictures, it could also help.
