Your site's looking good and working well from this end! Nice one.
Yes, WebAssist does some great software - made things possible for me I wouldn't have considered trying before, and speeds up other processes that would have taken me much longer to complete (apart from CSSFormBuilder which does the opposite for me!).
Don't be afraid to try stuff out though - the support here is good, and it's always a good idea to back-up your pages before making major changes.
Come back with any problems you have.
