It's not really clear what you are asking for.
About the best Word would let you do is type a numbered list of references
and then put the numbers in the text by using cross-references to that list.
You could maybe use the same principle for author's names instead of
numbers.
But it kinda sounds like you want the functions that you get from
bibliographic management software such as EndNote, ProCite, Reference
Manager, etc. In such programs, you put all the bibliographic info into
EndNote (for example), then in the Word doc, you insert a field code for a
particular citation, and EndNote comes along later, formats the field as you
wish, and generates a bibliography at the end from all the citations you
used. If you are writing a Ph.D. dissertation, it's probably worth buying
such a program, use google to investigate.
