I’m gonna order free samples as I am a poor student but which of these should I be ordering?

PIC18F452-I/ML

PIC18F452-I/P

PIC18F452-I/PT

PIC18LF452-I/L

PIC18LF452-I/P

PIC18LF452-I/PT  

oh and another thought is there any other chips I can order for the other modules from samples.microchip.com?

PIC18F452-I/P is the one, you need the “PDIP 600mil” package ones (PIC18LF452-I/P works as well, this is the low voltage type)

You can also order the bankstick ICs: 24LC512 or 24LC256 (also PDIP)

cheers!
