Good morning, Marvin;
" . . . a pile of Spectra 2-packs for $2.50 each." Oh, you do know how to make others jealous.
Go ahead and start out with the normal settings on the camera and see what comes out. If the result from the developed print is not what you like, make an adjustmet to the camera to see if a change in exposure (hopefully in the desired direction) will produce a print that works for you. Please keep in mind that the film is getting a bit old now, and it might not perform as stated on the package label. Try it anyway. It can be fun. Regarding your supply of film, do not freeze them. They can be refrigerated and that will prolong their life, but do not freeze them.
There is still something about watching a developing Polaroid print come up in the paper sitting on the table before you. The digital photographs of today do not really have the same "magic" in their ways of producing a print, even though it does not take very long to be produced. Getting prints from film normally was a two to four day delay, until the one-hour photo stands came out. The Polaroid (or even the Fujiroid) is still faster. Seeing it on an LCD screen is not the same. And, I do need to get some Spectra for my Minolta copy of the Polaroid Spectra Pro.
Enjoy; Ralph, Latte Land, Washington
