What taxes should I expect to pay out of my employer paid std/ltd at tax time? Will it be the usual % of federal, state, local, ss, and medicare? Thank you

I live in PA. I'm trying to get an idea of how much to set aside from my std/ltd for taxes next year. I'm also trying to find out whether my medical/dental will continue to be deducted as long as I'm on employer paid std/ltd.
