LL,
While buying the "package deal" may seem nice, I've found that the parts are either not needed or aren't the right fit for your needs. I have a SOT kayak and am glad I didn't buy an outfitting kit 'cause I discovered that there is no good place to mount paddle holders on my yak. There is a paddle slot, so I just mounted a hook (a nylon pad eye cut in half) and a loop of bungee cord too hold it in place.
As for the anchor, use it in still water only, as it could get caught up in current, which can have dire consequences. My anchor (used only in still waters) is two 2 foot sections of heavy link chain, covered with bike tire tubes (to help with noise and to prevent snagging in submerged brush). I use a retractable dog leash as my anchor line so I don't have to deal with a pile of rope in my lap.
I'd suggest you fish out of it for a while to decide where you'd like things like rod holders, anchor cleat, etc. Most hardware is mounted with either screws or rivets, and though some can be removed, your then left with filling in the hole :-( Be watchful of where your fly line hangs and try not to mount anything there so you can avoid it catching on things.
Here's a good site for buying hardware and such.

Enjoy your Pungo. It's a great kayak.
