The top few of my top hash performing operations have a select statement starting with top 100 percent. Does this have any effect from the same query with out the top 100 percent?

Shouldn't make a difference. Certainly won't cause a hash-operation. Probably they're queries someone 'wrote' using enterprise manager, which puts that in by default.
In the exec plan, you should see the top as the second- last operation just before the select.
As for the hash operations, post one of the queries and attach the execution plan (saved as a .sqlplan file). I'll be happy to look at it.
