This is a very interesting read on english grammar.
To the TS, "My wife and I are considering ............." is the correct grammar. Always put youself, that is "I", at the end, eg. Mr/Mrs XXX and I, my GF and I, etc etc. Also, it doesn't matter if the ending subject is singular, with AND as the connector, it's always plurar verb-to-be. But I remember there are some exceptions which I can't get it off my head right now.
As for the "ANY", I always hear words like,
"any doubts?" but not "any doubt?"
"any thoughts?" but not "any thought?"
"any coins?" but not "any coin?"
"any loose change?" but not "any loose changes?"
"any meetings?" but not "any meeting?"
"any money?" but not "any moneys?"
"any time?" but not "any times?"
"any fish?" vs "any fishes?"
"any chair?" vs "any chairs?"
"any seat?" vs "any seats?"
"any ticket?" vs "any tickets?"
"any idea?" vs "any ideas?"
"any solution?" vs "any solutions?"
"any preference?" vs "any preferences?"
"any more?" but not "any much?"
"any how?" but not "any hows?"
"any where?" but not "any wheres?"
"any body?" but not "any bodies?"
"any thing?" but not "any things?"
"any one?" but not "any ones?"
Okay, the last one is meant to be cheeky, but as far as I can remeber, noun after "ANY" need not be singular always, it depends on the noun concerned. Correct me if I am wrong.
Have attended lessons from SG, US and Australia, both "any question?" and "any questions?" are used by the lecturers/tutors. So I guess both could be correct.
Also, "does anyone has any questions to ask?" should be "Does anyone have any questions to ask?".
