Talk to your Plano tl. There isn't much to be taught about adset. You take down ad, you put up ad. Scan end caps to make sure all ad is out. Unless you are doing the set up the week before. Then you'll definitely have to talk to the Plano tl.
You'll be organizing signs by aisle, section, etc. Printing signs that come in, scanning signs with no locations. It will feel overwhelming at first, but you'll have it down in no time!
It is fairly simple. There are two shipments of 3x3 signs (usually there by Tuesday and Friday) and two shipments of 7x11/11x11 (Wednesday and Friday). Sort the 3x3s by block and put into boxes. Then take the ad correction (Friday box) and insert/replace signs. There will be signs with a POG number that you'll need to scan for locations.
There is a guide on Workbench: Processes/Sales Floor/Promotional Signing.
