Re: Good or well
These guidelins will handle 95% of your situations:
With any form of "to do" use "well" unless you are talking about charity/good works, where "doing good" uses "good" as a noun.
With any form of "feel" use "good" unless you are talking about your literal, physical sense of touch; "I don't feel well" is idiomatic to mean you are ill.
Most other verbs will use "well."
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
