Roasting Green Samples in IR-7

[CanyonCoffee]

I am somewhat new to roasting, I just purchased an IR-7! I am in the process of geting some Green samples from various sources. So here are my questions.

What is the best way to get a quality sample roast with the small amount of coffee they send you?

Is there a general practice to determine if it is a good coffee that is worth purchasing larger amounts?

Any information will help

Edit

I made a typo. Of course the way to determine is by cuping. But is there anything that I should pay special attention to while cuping?
