I believe they were animal skins. In fact, I believe it was either a goat, ram or lamb.
I believe that God disseminated some truth to Adam and Adam taught it to Abel. How else did Abel know what would please the Lord?
Gen 4:4 And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering:
Of course the Lord could have spoken to Abel, directly. He did after all speak to Cain, directly.
Gen 4:6 And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen?
I don't think the Lord will be building a Temple or House for Himself in the Millenium. Afterall, He has been building His House for over 2,000 years. There won't be any need for a sacrifice since He was the final sacrifice that pleased His Father and no sacrifice can make anything better than what Jesus did. His sacrifice was PERFECT.
