If it were my rig, I'd first go with slightly bigger tires, then a mild lift.
You could put some larger tires on it. I run 235/75/15 tires (roughtly 29") on it. Not too big, but a good upgrade from the 205/75/15 stockers.
A 2" lift is a great way to go. Nothing wrong with spacer lifts as they're inexpensive and easy to install, too. You could also go with a 2" spring lift as there are a number of companies making these (BDS, Calmini, Old Man Emu, etc.).
I not all that familiar with the 1.3-liter engine, but assuming it's similar to the engine in the Samurai, there are a host of upgrades you can do to it to make a bit more power, too.
