Looking for Somone Who's Changed a Charcoal Canister

I need to replace my charcoal Canister. The book shows you have to take off the O2 sensors, the exhaust, drop the tank, etc....

My mechanic friend wants to rent out a garage with a lift to take the tank out. Mine is an 07, I see on the internet a guy doing a 08 with the canister being able to get up there and take it off without dropping the tank. Is a 08 totally different then an 07?

Has anyone got one out with out dropping the tank?

I see my year has a primary and a secondary. Why did they put two on ours? Do we need to replace both of them? Most important, do they both do the same thing?

Thank you,
