This is found in the PBP manual. States that anything over 9600 will need greater than 4mhz.
Yes, you really do need a MAX232 and it really does need those capacitors.
Depends on what you are doing if you need a level converter. The PBP manual tell when it is common to use it. Caps on MAX232 = DATA SHEET
Yes pull up resistors are part of your life now. No one mentions them, but they're assumed in a bunch of different places.
Again the PBP manual and all over this forum.
The number of port you are going to have problems is directly related to the number of functions the port can perform. Pick a port for general I/O that does A/D or comparitor function (let alone osc or other) and you'll be searching forever for the commands that turn it off.
The manual and this forum and the data sheet.

So... you are basically saying that you did not read a whole lot.
