Do Jewish believers in Jesus have a special calling from God to maintain and proclaim their Jewishness as a distinct and separate entity from other believers? Do Jewish believers who worship at Gentile Christian churches pose a barrier to witness to their unsaved brethren?

I consider it very important, for the sake of maintaining a Jewish identity, to have worship services with a Jewish expression and to raise one's children in a Jewish environment. However, while I think it is important, I do not see it as a biblical imperative or divine decree for all Jewish believers. I realize many Messianic Jews disagree, but they would be hard-pressed to prove it from Scripture, as it is really an issue of personal preference – certainly important to one's Jewish identity but not a mandate from God. And, no, I do not think Jewish believers who worship at non-Jewish churches are a barrier to their unsaved brethren. The fact is that most Jews who come to faith in Messiah do so through the witness of Gentiles who are members of churches. When it comes to the issue of sharing the gospel, I see no difference whether a Jewish believer comes from a messianic congregation or from a church. It is yet to be proven that one holds any advantages over the other.
