Saints and saints days are recognized in the Episcopal Church, as you might tell from the number of churches named after them. However, they are viewed as holy people to be recognized and honored, but not as intercessors. So Episcopalians do not pray TO saints. A prayer ABOUT a saint will be to God in thanks for the example and witness of that saint.
Most Episcopal churches do have religious decorations of some kind or another, some may even have Mary chapels, though they are not venerated in the same way as in the Roman or Orthodox traditions. Statues of St. Francis in gardens are very common. It is not unusual for people to wear crosses or crucifixes to Episcopal services, and very common for them to be worn by the vested participants in the service.
The Episcopal Church invites all baptised Christians to share in communion. You should be aware, however, that the Roman church does not recognize the validity of Episcopal sacraments--but that lack of recognition does not go both ways, Episcopalians do not dispute the validity of Roman sacraments (but Episcopalians are not welcome to participate in Roman sacraments). Despite the position of the Roman church, Roman Catholics have often participated in communion in my Episcopal parish, and I believe this to be common elsewhere.
Although sharing in a common cup is usual in the Episcopal Church, the sacrament is equally embodied in the bread as in the wine. You may leave after receiving the bread, or remain at the rail with your arms crossed over your chest to indicate you do not wish to partake ofthe wine.
You may also take communion by "intincture," which is dipping the bread into the wine. This is handled differently in different congregations. In some, you hold the bread in your hand, and the chalice bearer will dip it for you and place it on your tongue. In others, the chalice bearer will hold the cup while you dip the bread (or wafer if that is used). There is absolutely nothing incorrect about taking communion in this way. It might be a good idea to ask the rector as to how this is usually done in that parish.
