Usually on submodels you can tell which they are by....
2wd=JA
4wd=JS
power windows and locks=JLX
"leather" seats=Limited
There are other "options" that are usually included in JS, JLX and Limited models, other than what I listed above. Sometimes the submodel designation is also on the tailgate.
For your clutch issue. Sounds like the cable might be bad (it does happen on new ones, especially if it isn't a genuine suzuki cable). If you still have your old cable around, swap it back on and adjust it and see if it shifts easy again. I would not drive it with it shifting like it does now...you could cause damage that will cost a lot more time and money to fix.
