To transport your kayak, you'll need some way of securing it, whether on a roof rack, truck bed, or trailer. I recommend the type of tie-down strap shown above, with hooks on the ends, and cam buckles, not ratchets. Ratchets are a pain in the ass, and you don't need all that much force anyway. In fact, you don't want too much force, your boat is only made of plastic!

Your new boat probably came with a paddle. I've never seen a boat come with a good paddle. It is just a starter, to get you going. Get a good paddle that is the right size for you. It will make a world of difference. Keep the old one for a spare. Rule of thumb: your paddle should be at least your height. If you install a thick seat cushion, you might want to go a little longer even.
I regard my paddle as an emergency signalling device as well, which is why I like the yellow color pictured, especially if your boat is some camouflage shade of green. The paddle above is about $50 at Dick's. I really like it. No sense hobbling yourself with the piece of junk that came with the boat.
