2.  Do what Christians do---love.
The part of church reform that we usually think about when we talk about "church reform"---the adoption of constitutions and statements of faith, the election of elders, and all the rest---is really only a fraction of it.  At the end of the day, reforming a church is mostly about doing the things that Christ expects of his people:  loving the saints in your church, pastoring them even when you're not the pastor, teaching them publicly when you can and with your life and words all the time, and sharing life with this group of Christians with whom you have covenanted. 

Reforming a church can take years, and it is never something that happens easily.  So settle in for the long haul.  Love, teach, exhort, encourage.  Share burdens, sorrows, and joys.  Talk about the gospel, and help to apply it to your fellow church members' lives.  There's a real danger in trying to reform a church that it will devolve in your mind into a project---a series of parliamentary steps that have to be run through---rather than a group of people who have professed faith in Christ and are struggling to be like Him.

Ultimately, the reason you are a member of a church is to encourage your fellow saints, to be encouraged by them, to spur them on to good works, to be spurred on by them, and finally to see everyone---yourself included---grow to maturity and completeness in Christ.  That's the goal.  Formal church reform is merely a means to that end.
