Regarding the first question, the Code of Canons for the Eastern Churches states:
Canon 35 - Baptized non-Catholics coming into full communion with the Catholic Church should retain and practice their own rite everywhere in the world and should observe it as much as humanly possible. Thus, they are to be enrolled in the Church sui iuris of the same rite with due regard for the right of approaching the Apostolic See in special cases of persons, communities or regions.
Canon 36 - The transfer to another Church sui iuris takes effect at the moment a declaration is made before the local hierarch or the proper pastor of the same Church or a priest delegated by either of them and two witnesses, unless the rescript of the Apostolic See provides otherwise.
In other words, converts from Eastern Orthodoxy are expected to join the corresponding Eastern Catholic Church (whether that be Melkite or Chaldean or what-have-you). It's possible to transfer to another Church (such as the Latin Church), though it's generally discouraged and requires permission from the hierarchy.
Regarding the second question, I know some Eastern Catholics who have freely adopted some devotional practices of the West, such as the rosary and Eucharistic Adoration, and have found them to be harmonious with their own traditions. Conversely, while belonging to the Roman Rite, I use Byzantine icons in my own private devotions and see no conflict whatever with Western spirituality. Though some may disagree.
Sigh If you elect to quote canons as a [very inorganic] response, one might as well be consistent with legal language. You are not "expected" - you are automatically inscribed. A rescript is possible. Both more succinct and consistent in terms of diction.
That being said, I continue to be perplexed by canon-citing existing as the most proliferated form of "discussion" in this sub-forum.
