I agree when you say that shaytaan will come upon us from all sides...because if you were doing good for people to see you and think that muslims are good people, then they would be unaware that you just want them to see you and think good of muslims, ie that is your true intention, because being good doesn't mean that you want people to think of you as good, rather if Allah thinks you are good then you are good. So the main thing would be to keep in mind the intention of pleasing Allah, because there are some things you do to please Allah that will make non muslims think you are good, eg giving charitably, but if you gave secret charity and a non muslim didn't think you were good, what would it matter? So then it comes down to da'wah, I think da'wah is mainly from the religious aspect, ie telling people about jannah and jahannam, and about Allah, angels, prophets, qadr etc....and many non muslims think that muslim men look down on women or mistreat women, and are violent, so as long as these two things are avoided, then that's about it...not sure if this made complete sense, but that's what i think.
to summarise, we should fear God, do good deeds that please Him. may Allah guide my family to islam, ameen. say ameen please
