Cash game donk needs help

[GSykes]

I used to play tourneys and SNGs mostly low buyin <20 FO and 3rebuy. I had ok success but switched to cash games.

I am just looking for a quick refresher to go over before I head to turning stone and add 1k in dead money to the tourneys.

I own the first 2 Harrington books would the third be an excellent refresher course?

Basically I have 2 weeks and don't want to spend the whole time reading on how to play tourneys as I am using it for limited use (3) but would like to dedicate a day or so to sharpen the skates.
