There are quite a few that go to the gas shocks, or struts, over the air filled, I personally went with air struts as I like to keep things as OE as possible.
If you convert them the conversion kit, with a decent pair of gas shocks plus hardware needed, will be about the same price, all you do is unplug the unit that I believe is under the driver seat.
Check RockAuto for the MONROE part # 90007 , 102.79 plus shipping for the conversion kit/pair.
Here is that same gas shock kit from Amazon, with free shipping.
They mention if the OE Absorber has threaded fittings then you ACDELCO Part # 19210500, I don't think you'd need them, but I am not familiar with your cars shocks, those shock mount kits are 50.00 per kit and you'd need two, so hopefully if you want to go gas you won't need those mount kits, maybe somebody here more familiar with your car can let you know for sure if yours are absorbers are threaded or not.
The air shocks I recommend if you are staying with the air shocks are these.
Some tips, if you keep the air shocks, look in the rear of the car, somewhere near the muffler, or in that area, you should find the compressor with some EVAP hoses connected to a T on it, unless it is totally different on your car, if you can find that compressor, remove the lower hose from it, and use something like the following to get a few drops of light machine oil inside the nipple, then put the hose back on.
I only lube mine every time I do the engines oil, it helps to keep that from failing sooner.
Here is what I used to oil mine.
