With regard to Vls.... I think (correct me if I'm wrong Aomic) Atomic means config and bank angle, as for load factor in wings level no change but while in the turn then your Vls will incrase. The side stick is demanding a constant load factor of 1G and only if Abruptly used will you increase your load factor.
As for mode engagement... I'm not quite sure of your question, but I'll try, you can select or manage speed without ever having activated the vertical (alt) mode. You can do this with AP engaged or disconnected, same is true for ALT modes.
With regard to Appr mode, I think I now get your question...... loc has no limit (with in reason 25nm or so) for engagement whereas GS is predicated on which RA system is fitted. Collins as far as I know use 5000' as a limit for GS capture.
Atomic.. correct me if I'm wrong but if during take off and V1 failure occurs there is no change in power setting even at acc alt. It is only activated (mct) after you move thrust levers out of the flex gate and back into to them.
