Yes, Brian, you can leave those components in.  I have done the exact same
procedure to my ZipGS.  It's been working fine for over a year!

When you install your new 4-pin crystal, be aware that it must be placed
near the bottom end of the socket.  

Good luck...please send me e-mail if you have any questions!
