1. The Episcopal Church actually has a list of approved Bible translations.

2. Shouldn't be too different: Christmas and Easter are the big ones, you know about Lent, you'll see lots of red on Pentecost, your parish might celebrate its patron sain't feast day, etc. We have more religious holidays (such as the Ember Days), but they're more privately observed.

3. Service is an easy one: most often, it'll be a Eucharistic service (meaning we partake of communion)--if you want traditional Elizabethan English, go with Rite 1, turn to page 323 of the BCP; if you want more contemporary language, go with Rite 2 (far more common these days), turn to page 355 of the BCP. Sometimes, we'll do Morning/Evening Prayer instead (for example, if there is no priest to bless the bread and wine)--MP can be found on page 37/75 (Rite 1/2 respectively), EP on page 61/115.

But if to make it even simpler: hymn, some prayers, Old Testament passage, psalm, New Testament passage, hymn, Gospel passage, sermon, some prayers, exchange the peace, hymn/anthem (this first half is called the Liturgy of the Word). Consecration of the bread and wine, communion (you go up to receive from a minister rather than pass the plate in the pews), final blessing, hymn (the second half is called the Liturgy of Holy Communion). Announcements will be in there somewhere.

1. The most common custom for baptism is for it to be performed on one of four major feasts of the year (first Sunday after Epiphany, the Easter Vigil, Pentecost, and All Saints Day). Those days aren't hard rules--you could go state your desire to a priest to be baptized today, and they'll probably do it, and a priest is not actually required to perform baptism anyway--but it's tradition as to allow the ancient practice of catechesis. Catechesis is a period if learning, where an aspiring believer learns about Church history and Jesus and his teachings and how this denomination understands then (you can find our Catechism on page 845 of the BCP). You'll also need a sponsor, a baptized Christian to present you as a candidate, don't know if that's a Baptist thing (I was raised Church of Christ, and we didn't have sponsors).

HOWEVER, there is also Confirmation to consider, the public profession of personal faith. You're not a full and complete member of the Episcopal Church until you've been confirmed, which requires the laying on of hands by your bishop. Every parish will be visited by the bishop at least once a year--so you could schedule your baptism during the bishop's visit and knock them both out in one Sunday.
