I think you'll see more of a push in January for more recruits. I know they are on some JUCO kids that I believe are mid-year, so they would be eligible for spring ball. I know they're looking at some JUCO DB, OL and possibly a QB. Not sure how serious we are on some of the kids. As per usual I think you'll see some very successful weekends in January.
As it relates to hosting kids during playoffs, you definitely can until the quiet period as far as I know. I haven't looked at any of the quiet/no contact time frames for this year though, so I don't know when they start.
