Theist != Christian
Also, stands2reason, what do you mean by posting "theist!=Christian". It's my understanding that a theistic evolutionist believes that God worked through evolution to bring about the world as we know it. Is that a correct definition?
Did plant death happen before the Fall? How about cell death?
If life now is exactly like it was for Adam and Eve, there would have to be cell death, but isn't cell replacement a requirement to keep a human living, not to have them die. Our dead cells aren't replaced as we age, so perhaps there was no need for replacement for Adam and Eve because they were not heading toward an ultimate death (before the Curse).
Plant decay...Like my answer above, if life now is exactly the same for Adam and Eve, then there would be decay if several days go by between their creation and when they are trampled on, or however they meet their end. But there is no way to know the conditions in the Garden of Eden, except that it was "very good".
My biggest "hang up" is with the human beings though because that affects the rest of the story of the Bible.
