Serial might not be your best choice but, if you can implement
hardware flow control on the arduino, it can be made to work.
I would try parallel: an 8 bit port managed by one end of the other.
SPI is another possibility as long as the OOPic can be the master.

No, the OOPic is always a master on the local I2C bus - the one with
the EEPROM. The OOPic will appear as a RAM to other devices.
Getting the proper address is an exercise for the reader.

Maybe; that uses an OOPic specific protocol. Grab the
OOPicI2CTools.zip file from the Files section and see if it helps.

Yes

OK, I gotta ask! If you are using the Arduino, why do you want to use
the OOPic? Even if you just needed more IO than the Arduino Stamp,
it would be cheaper to buy another Stamp than to buy an OOPic.
In either case, Arduino or OOPic, you are forced to do things they
way the designers allow. At some point, it is easier to bite the
bullet, learn C and just use a standard uC.
The OOPic is great at what it does: rapid prototyping. It isn't
great at serial IO or even communicating with other uC's including
another OOPic.
Having never used the Arduino, I'm not sure what it does best but the
Stamp is an interesting device.
There's room in the marketplace for everybody!
