Noob questions re:Mission Bay Quivira Basin

[pbb]

I am planning to give kayak fishing a try (for the first time) in Mission Bay tomorrow. My plan is to rent a yak from Aqua Adventures in Quivira Basin, and to fish around the bait barge and surrounding areas.

Any advice for a noob?

I am bringing swimbaits and I have grubs. I have light iron. I can't claim any great experience actually catching fish on any of these.

I figure I could also buy live bait at the bait barge (or try to jig some on a sabiki) and flyline that, which I at least have the experience of doing in the party boat environment.

(I have a battery aerator for a bait bucket).

Any suggestions to make my first time out successful?
