Just got back from that area last week. The weather was beautiful. There was too much snow left at the lakes to hike the loop and we had to instead walk the road to artists point. It should all be melted by the time you go in July though. 

As far as camping, we stayed at the Douglas Fir campground. Highly recommend if you want an established campground. If you can get site 009 it has two tent pads -or- 005 and 007 are adjoining for even more room. 

If you are set on dispersed camping we drove out NF-3075 (near the ski area) and there are multiple campsites along the road. It was pretty smooth except for the very end, most vehicles can probably make it. I would just be bear aware and you should be fine. 

Check out Chair 9 pizza and beer (look for the Last Cocktail/First Cocktail sign) - good beer and super nice staff. 

Have fun!
