If you need to use RA.2 and RA.3 then you'll probably want to leave off the MAX232 for now (you won't need to install the four 1.0
caps either)  If you only need one of those and can use RA.3 (TX line) then leaving the MAX232 onboard won't hurt a thing.  

The EEPROM just plugs into a DIP socket.  What you may want to do is mount your DS1302IC on a 8-pin machined pin DIP socket and just wire up the appropriate pins on that so you can plug in that or the EEPROM.  I've just looked at the datasheet for the DS1302 and you'd just need to bend up leads 1,2,3, and 7.  pins 2,3 can get you xtal, pin 1 a cap to pin 4.  The whole little 8-pin DIP module plugs into the EEPROM socket.  With that just add a small jumper from pin 7 to RA.3 on the MAX232 and you should be all set!
