manual lens usage question

I have question related to change of setting to help use of manual lenses in modern DSLRs.

I understand I need to enable 'other than A setting' when using manual lenses, my question is when I want to use an auto lens after this, do I need to change the setting back as how it was before or that doesn't matter - by that I mean can I still use the auto lens while leaving the setting at 'other than A setting'?

They will continue to work just fine.

I believe Pentax has this counter-intuitive control set as it is to avoid problems with 'green button' users putting on a aperture ringed lens.

I tried an old 50/f1.7 but no matter the apreture setting, it woud not make an exposure. Maybe a bum lens. Worked fine on an ME.

I understand the manual lenses (M)can only be used in M mode. And by that I presume I have that ability to change the aperture size and shutter speed - somebody please confirm.
This doubt stems up from when i read that pressing of green button automatically generates the right shutter speed, I still be able to tweak the shutter speed? since the contracts at absence on the mount how is this achievable?
pls also share as many advices in the use of M lens on DSLR I am waiting for my copy of first M lens.

Yes after you push the green button the camera learns the exposure you can change ss to change exposure, dont push green button again before taking shot
