Thanks chaps. I knew what modes I should expect in a normal manual go-around. What I was trying to figure out was if these modes were affected by being in N1 mode. There are lots of references in the manuals to how the modes relate to SRS, but if you aren't in SRS due to the downgrade then do the modes change? It would seem not. I suppose once you reengage the flight directors you're out of what would have been the SRS stage of flight and so normal modes still apply.
Good point about overboosting the engines. Haven't had to worry about that since my turbo Arrow days. I suppose in a normal go-around with Aa at 1000ft aal you'll get the lever climb prompt after about 20-30 seconds so the chance of any damage should be minimal even if you do over boost. Not a lot you can do about it anyway as the priority is getting away from the hard stuff. I certainly don't want to bring the power back too close to the ground.
