Can I add pull up resistors to my Attiny85 and AVR programmer?

I am using Attiny for pulse width modulation and I wonder if it is incorrect to add pull up resistors for my attiny and avr programmer.

I would think pullups are a good idea. Having port pins floating may not be.
Is the programmer removed or always connected?
And, does the programmer drive the ATtiny reset pin? If so, R3 man need to be connected to PB5, not +5V.
