Actually, this off-season is going to be a really tough one for AA, because the risk factor in ALL of his moves now has skyrocketed with the regression of Romero and the poor play of Johnson and Escobar. He may be forced to simply go with the kids because there are no better options given the lack of respectable options at cost. This despite AA's preference to let the kids play in the minors for longer in all of his interviews.
I don't think much has changed as far as AA's priorities with the offense, to be honest. It was pretty evident last off-season that AA didn't want Johnson back and was ready to move on before KJ decided to accept arbitration. It was equally clear, for whatever reason, that the club had no intention of developing Travis Snider, so an upgrade at LF was going to be an issue in 2013 as well, unless Thames hit well (which he didn't). Now it appears Hech is guaranteed a spot next season (either at 2B to team with Escobar or at short to replace Escobar) and Lind+his contract are going no where unfortunately, so really LF is the main issue. I think AA was always banking on internal development with the offense, for better or worse. The team was going to go as far as the development of Lawrie/Rasmus, the continued MVP-ish performance of Bautista, the high-OBP of Escobar, etc. Unfortunately, most of those guys regressed while only EE took a step forward. I don't think much will change with the offense. AA will likely still bank on the same young group to produce on offense, except hopefully he adds a capable LF to make up for what looks like potentially 500-600 AB's for Hechavarria (I like the Shin Soo Choo idea).
The main stumbling block to 2012 was the starting pitching, as Drabek got hurt, Hutchison got hurt, McGowan (predictably) got hurt, Cecil didn't regain his 2010 form, Romero regressed badly, Alvarez was clearly not ready, etc. I'd imagine AA already knew, or at least suspected, that LF/2B was going to be an issue in 2013, but the real problem became the rotation as practically nothing other than Brandon Morrow seemed to work out. That is where I would assume most of AA's attention will be, especially now with his fetish (the bullpen) not really needing any more help.
