The information you need is on FCOM 4 (4.5.30 Flight phase related procedures / Take off / No Flight director Take off pag 5). Basically i guess that as stated before in this thread there is no automatic a/thr arming when you set toga or flex, and since the active range of the a/thr is from above idle to clb (or mct with one engine out), while you are outside this range (ie.Toga) you'll have appropriate indication on FMA, probably when you set CLB you'll get no indication on FMA whatsoever... I've never tried such proc. It'd be good to have a go on my next sim session...
As for raw data approach, I think there's nothing wrong about it... Where I fly there are a few airports with no ILS, so we make visual approach very often, "AP..off" "FDs...off" "Birth...ON" and that's it, fly the appr like a cessna... Also when weather is ok and there's no much traffic around, I like making raw data ILS and I dont really think that dowgrades safety at all.. I think that its good airmanship to be trained for hand flying the aircraft in any condition...
