Upgrade to 59 dollars plan only if you need the extra ahemmm SMS and extra call time. Else it's just plain stupid to get the accessory pack for pay $20 monthly cos even if it really cost $146, you just look at how much extra you need to pay over 2 years.
FYI i got for my friend the extra battery kit for S4 from Qoo10 at around $40 and i'm sure the dock ain't gonna be $106, you should just keep to whatever plan you have, then wait a couple of months for the Note 3 accessory pack to be widely available online then go buy.
*disclaimer - Dun blame me if the Note 3 battery kit end up more ex even after 1 year
