Church Membership. Yes or No?

I believe I would be in sin for not becoming a member of the church I am attending. Although not a Calvinist Church, I am in a locked situation where this is the church I am attending (long story). They hold to the essentials of the faith but we disagree on secondary issues such as the following.

Music- They are traditional hymns only while I prefer more contemporary tunes, but not necessarily a charismatic rock n roll NewsBoys concert.

Bible Translations- They only use the KJV while I prefer the ESV/NIV

Ecclesiastical Separation- They only associate with IFB and Fundamental churches, while I would associate with Bible churches, the SBC, and others as long as they hold to the essentials of the faith. Note- I would not associate with Charismatics nor Pentecostals

Alcoholic Beverages- Drinking in moderation is okay.

Calvinism vs. Armianism.

Since most on this board are Baptist can you present the argument of those that do not believe in Biblical Church membership such as the Plymouth Brethren? If you cannot then I must conclude that I need to be a member of this church as long as I do not cause division over disagreements on the secondary issues I mentioned above.
