The plugs that have already been recommended will get the job done but I would also invest in a low cost set of earmuffs (and use the plugs along with the earmuffs).
The Remington M-24 earmuffs are rated 24dB and cost $9.99 on midwayusa.com they are not the best on the market but they are cheap and will get the job done especially when used with earplugs.
I have a nicer electronic setup with higher protection and I still use plugs. If you don’t like the plugs that were listed and still want something cheap you can pick some up at your local range, hardware store, and even most convince stores.
As for eye protection most anything will do just make sure they fit your face nicely, won’t fall off, and don’t leave any spacing above your eyes or temples (you don’t want hot brass bouncing off a wall and getting wedged inside your glasses).
I would even try to purchase those items from my local range. I am sure they will be more than happy to recommend some products for you as well. Just be clear that you don’t have a lot of money but want the most protection that you can afford.
Be safe and happy shooting!
