The C64 uses dynamic ram, 64K x 1.  The machine runs its ram refresh pretty
slow by today's standars.  I have seen Drams rated at 300ns used in the
C64 logic boards.  200ns to 150ns is typical.  
 
As for your analog paddel port, I have worked with it myself once, and
I dont have the spces, but its easy to access it via the sid chip.
