Take a look at Table 9.1 on page 200 of the TINI Spec 

http://www.ibutton.com/TINI/book.html

That describes the port pins and their various uses. The short answers
to your specific questions are:

1) No you cant the p5.2 and p5.3 as GPIO if your using the external
1-Wire master.

2) Yes, if your not using CAN or the 'built-in' I2C you can use p5.0 and
p5.1 as GPIO.

Hope this helps.

Don
