ShinSect Fighter: Versatile Battery

[Azurift]

Versatile Battery (Ex): While a simple weapon on its own, with a little creativity and know-how, a club can many tricks other weapons would find difficult. At 2nd level, a shinsect may, as a free action at the beginning of each turn, choose up to two of below traits to apply to any clubs he wields until the beginning of his next turn. At 7th level, he may apply three traits, and at 14th level, he may apply any number of traits he wishes.

Blocking, Disarm, Grapple, Nonlethal, Sunder, Trip

Disarm, grapple, sunder, and trip are all combat maneuvers -- does this ability imply that the ShinSect gets a free attempt upon each successful attack? What happens in the case of the "nonlethal" and "blocking" traits?

Also for Viladin: Small Arms Expertise for ShinSect does not explicitly state the level at which it is gained -- is this intentional?

No, they're weapon qualities: http://www.d20pfsrd.com/equipment/weapon...-Qualities

Small Arms Expertise is gained at 3rd level, same level Overhand Chop, but I'll add a note.
