Yeah, as people have said, the 734 is the right rod, it's a great all round rod, and would be a good buy if you could only get one at the moment. Or you could do that 704 if you want a little shorter, as some kayak guys prefer. Pretty much whatever braid you want will work with that rod, i'd stick with 30lb-65lb.
Just make sure you have somewhat of a plan about what rods you are getting (beyond the first one) before you pull the trigger.
