Hi. I have tried out a few cases and the best so far is the official Samsung Protective Standing Cover. It is around £30 but definitely worth it. It's got two little legs at the back so you can stand the phone at two different angles. Otherwise, look for Spigen cases on Amazon, they are not as expensive and they are good quality.
About screen protectors, again, try Spigen ( they do a 2 pack one ) - this is what I am currently using right now.

Hope this helps.
