Drop extra wild shape, and if you wanna keep the flavor get fast wild shape (CD). 4 uses of wild shape /day is already enough since the average campaign has 3 battles and one good chance to use wild shape for utility forms /day, plus some extra from time to time. And you don't need to wild shape in any battle, spells can be enough. Also if you need to wild shape, being able to do that as a movement action instead of a standard one helps, even more when you are babysitting as you don't want to leave the other characters alone for a round. Normal wild shape means that in a round you can wild shape and move. Fast wild shape means you can wild shape and cast a spell, or move, or attack if already at range, or other stuff.
Get a studded leather armor instead. Minimal effort for a slighty better armor.
The croc is a good grappler, but not at level 11. If you don't need it normal sized get a giant crocodile instead. Or even better an allosaurus if you don't want to stick to crocodiles. This is assuming you want a grappler.
I never equipped a druid with 60k gp, so I don't know lots about that.
However, since the druid is not object-intensive as other classes, remember you can buy equipment for your animal companion too. If you keep your normal crocodile, make sure to train him to be a warbeast so you can make him wear a barding (plus some other bonuses), unfortunately training stronger animals may be harder (mostly for background reasons. It's reasonable that you trained the animal you got 7 levels ago, not as much for an animal you got the last level).
Otherwise you can always make him wear other items. Just make sure to buy items that will fit your next animal companion in case it dies or you choose to change it. A collar can be worn by most animals, and wondrous items usually resize automatically.
