I'd also recommend a safety flag if you are out with a lot of boat traffic. I got the kids bike flag and rigged it for my kayak. Stands nice and tall and only $12. Unfortunately I don't have any pics of it attached.

I make up a fishing table-type-thing to attach rod holders and a few cleats to hang things off and tie off the anchor (folding kayaks don't have the option to drill in flush mounted rod holders or have the side tracks).
Lots of options for kayaks these days.
