It is fine to use them like that, it gives you more traction in sand. Plus, sand is a very forgiving medium for lockers. So no worries, wheel away (you can even go faster if you want).
I disagree with the post above about not going over 5mph with lockers. There is nothing wrong with lockers and speed, as long as you are in a deformable medium and you aren't doing a whole lot of turning. For instance, climbing a sand hill might require speed and a locker together. No problem there, that is what it is for, but as soon as you return to hard terrain and you have the momentum you need, locker should go off.
Upgrading to a D44 shouldn't be necessary with stock tires, but if you plan on going bigger than a 33, you should look in to a Dynatrac ProRock housing (much stronger tubes and more ground clearance than a Rubicon 44 housing). At the magazine I work for, we did everything possible to beef up a D30 housing for use with 37s. In typical Jeep use, that housing is already bent. It all depends on the usage.
