1) I have a program where I'm creating and deleting fields. If I try to delete a field that hasn't yet been created, I get a script error. So is there a way to first find out if the field exists?
Did you look up "exists" in the dictionary? That also refers you to "there is" operator in the "see also" section.
2) Other than creating a substack to overlay my main stack with a "Loading" field that adds a period after "Loading......" is there a way to lock the screen (so the user doesn't see the fields being created) and still show a field with the "Loading..." going on?
If you lock messages as well as locking the screen, you probably won't need to show a loading dialog. The display and update of the dialog is likely to take longer than just creating the fields. I can create 500 fields in under 2 milliseconds.
