how to arrange pew seating???

Typically family sits in the order they arrive. Once all the guests are seated the mother's parents walk in, father's parents, then your siblings not in the wedding party. Then your mom and step dad, and lastly your father since he will be the one walking you down the aisle I'm guessing. There are a bunch of different ways to do it. It will really be dependent on who is walking you down if anyone. This website may help you

I think typically you keep the first few pews reserved for family. How many pews depends how big your family is. You don't usually have reserved seats, just reserved pews. Family is seated as they arrive and right before the wedding starts both mothers are seated, signifying the start of the ceremony. You can also have your grandparents escorted down the aisle right before the moms, it makes them feel special.

Kimi K's order is correct, and like Savannah said, it is usual to reserve pews.

If it's a Catholic Church, the bride's family sits on the side with the statue of the Blessed Mother, and if it is the Groom's family, they sit on the side of St. Joseph. Well, that is how we did it in 1982 with a very old parish church.

I just googled. In Christian ceremonies, apparently, the bride's side sits on the left,and the groom's side sits on the right.

In Jewish ceremonies, according to my google source, the bride's side sits on the right.

We threw out the whole traditional "Bride side, Groom side" because we wanted the church to be evenly filled on both sides. The only reserved seating we did was for immediate family members (i.e. mother, father, grandparents). Everyone else got seated as they came in. Family or not....if you were late you got seated to the back. Now for the reception we did have assigned tables and family and close friends were seated closer to the front and to the BR and GR.

@Maria - I think I may do that. Both our families know both of us really well. And I feel like if the ushers asked, 'Are you here for the bride or the groom?' most of them would say 'Both!', haha. Plus me and FH have all the same friends so why would we split them all up because I knew one longer or he did?
