Fear not, CC is here!
Hatebreeder first off I'll answer your questions. Skinless are OK and are probably a good intro to brutal death. Dying Fetus are very good, as well as being another good intro band. I would suggest any album except Stop at Nothing. Vital Remains are not a band I really care for.
Now I'll give you some of my recommendations. I tend to split brutal death into two categories: "slam" and "blasting/tech". Slam is slower, groovier stuff while "blasting/tech" is surprisingly enough faster and more technical. Here are my favorites for those two categories.
SLAM:
Devourment - 1.3.8: This is a compilation of one new song, three demo songs, and the album Molesting the Decapitated. Everything on this is great. This is
the slam death album
Digested Flesh - The Answer to Infection: Some sick vocals and monumental slams.
Infected Malignity - The Malignity Born From Despair: More growly vocals and some sweet riffs mixed in with slams. Beware this band's new stuff however, as they pussied out.
BLAST:
Disgorge - Cranial Impalement: Amazing vocals and great riffs and blasts. Just a brutal album from start to finish.
Amputated Genitals - Similar to Disgorge. Cool riffs and good vocals.
Cenotaph - Pseudo Verminal Cadaverium: Endlessly interesting album where each song is an energetic ride. Familiarize yourself with the genre a little before listening though, it can be overwhelming.
I hope this helped. Tell my what you liked, I have plenty more recommendations where these came from.
