Just building on what others have said- if overlanding is your goal, then maintenance is your priority. Xterras are more than capable of most overlanding right out of the box - make sure that radiator is up to snuff, all the fluids are up to date, battery checks out, etc.... then you know you won't get stranded.
Once that is done - I think it kind of depends on your plans. I'm in Colorado, so any half way fun trail is going to involve at least one river crossing or deep puddle (especially this summer) so extending the rear breather tube was my first priority.
Now I know my truck is reliable, and I won't cause any lasting damage when my rear wheel drops into a hole I didn't see when I pre-walked through the river....
Then communication is probably next - most club runs require at least a CB, but if you do more "spur of the moment" type trips and trails, even a set of hand helds is valuable, you can hand one out to the other vehicle - quick and easy communication is crucial.
But none of these is very fun - so my very next mod, assuming the tires are in good shape, is sliders. They look cool, they are useful for standing on, and they will potentially save you some very expensive "whoops" moments.
Then I would just use the hell out of it. You'll find out very quickly if you need a lift, more lights, beefy bumpers, etc...
But boring stuff first - make sure you can get home without walking - so get that radiator looked into.
