Welcome to CS TC,
Sounds like you've got the bug!
Get to know your coffee making gear while doing research on the next step. Once you're
getting good results on the machinery you will be able to take the next step more easily.
The CS8/9 (CS=CoffeeSnobs) bit refers to roast colour and relates to a card (see BeanBay 'Other Stuff' for reference)
which is unfortunately sold out and will reappear "when it does, if at all". There is plenty about roast
colour on here and the web. Start looking in the 'Roasting, and 'Cupping Room' threads. Checkout some of the sites
you'll find when you google 'popper'. You will not be handicapped in any way by not having a card.
Ask questions, enjoy the ride.
