Yes, I have heard plenty of conflicting arguments on the freezing and the fridge thing.
Personally, I think that if you are buying fresh beans and use them within a week, then the fridge/freezer would be useless regardless of which camp you believe.
I suggest doing more research and reading a few more articles on this point, then make your own mind up as to whether you want to try it out.
As to the questions
1 - Re-sealable bags. Personal preference, airtight canister away from direct sunlight.
2 - I say no, but see above.
3 - Freshly roasted coffee is usually best consumed within the 1-8 week mark. Different beans and different roasts will have different sweet spots, but generally speaking, past 8 weeks youll be pushing to get the best out of it. It will remain drinkable for quite some time (hence long use-by dates on supermarket beans) but the taste will certainly be best prior to a few months passing by.
