By now you probably already took care of the necessary modifications... But, I would suggest to checkout some of the reputable 4-wheel and off-road stores for kits that may be suitable for your needs and for the tools required to install (i.e. 4wheelparts.com and several others).

No, air compressor is self provided. Some of these models have run flat tires, so no spare tires. If a tire has a 'blow out', no compressor will be able to help; if no spare on board, call for roadside assistance is about the next best option.
