We recognize Mary as Mother of God or Theotokos (God-bearer). Some Anglicans believe in the Immaculate Conception. Some believe in her Assumption into heaven. Officially, there is a lot of freedom when it comes to Mary. A lot of us believe the things that one finds in the Early Church about Mary, so practices like the "Hail Mary" prayer can be part of personal devotion. Some of the newer Catholic ideas like "Mediatrix of All Graces" or "Co-Redemptrix" aren't really a part of Anglicanism. We honor her and the Saints, but not usually to the Catholic level. Some Anglicans don't really think about her much at all. There's a lot of variety.
You might not encounter much of this in Sunday worship.
We do have Confession, but not every church or priest offers private confession. We have a corporate confession of sin and absolution as part of our Sunday liturgy. We believe that this is sufficient (an area where we differ with Rome). Some parishes do offer private Confession also. Both are acceptable. We don't necessarily think in terms of being in a "state of mortal sin" or a "state of grace," like Catholics do. Well some Anglicans might, but that's not really our usual mindset.
We do make the sign of the cross, although when & where might vary by local custom. Usually we do at the end of prayers, at the name of the Trinity, at the Consecration of the Eucharist, during the Absolution of sins, during a Blessing, and maybe a few other times. A lot of people make the Sign after they receive Communion, also. But there's no pressure. Often, converts from Evangelical churches aren't comfortable with it, and that's totally understandable (having been one myself!).
Every Episcopal church that I've attended has a great youth program. As long as they have the staff, they usually try to make that a priority!
