A set of 2” leveling spacers for a 2wd can be found for under $100 and are relatively simple to install. Be sure to have it aligned afterwards.
As far as wheels and tires...tons of options out there. One option to consider would be checking Craigslist and local Facebook buy and sell pages for factory takeoffs from newer Rams. All 1500’s from 02-18 have the same lug spacing so pick a set you like and run them. Most factory 17’s come with 265/70/17 tires which will fit fine (probably what you have now). If you find a set of 20’s, they will probably have 275/60/20 tires which are basically 33’s. They will fit fine if you level. The bigger/heavier the wheel/tire combo is, the more it will work your v6...but make the best of what you’ve got and enjoy your $900 truck.
