1) If one is to believe the theory of evolution, doesn't it throw out the teachings of the Bible?
No.
2) It sounds too convenient to say you can believe in evolution and be a Christian at the same time.
How it sounds is not really important to the issue.
3) How can you be both if the Bible totally contradicts the theory of evolution?
If that were true then you could not be both.
The Bible does not totally contradict the theory of species evolution. In my somewhat-educated opinion, the Bible contradicts the theory of species evolution only one or two very minor points or not at all (depending on the particular variation or "rider theory" of the theory of species evolution that is under discussion).
4) How can the story of creation not be take literally, it's very clear.
a - the clarity of a story does not by itself mandate a literal interpretation
b - as mentioned above, a very literal interpretation of the Biblical creation story only disagrees with the theory of species evolution on one or two particular points...sometimes (again: depending on which variation or aspect of the theory of species evolution that is under discussion)
5) If you don't firmly believe in one thing in the Bible, there is no reason to believe in anything.
I think you might want to reword that.
Remember: the basic premise of the theory of species evolution is this:
"The reason - the cause - of multiple species on Earth is species evolution"
Nothing in that "thesis" excludes God or Godly creation.
