A couple more hints to help (help?) you along...
I built a 4x4 quilt sewing table out of 3/4 inch Birch plywood. In one corner (to the left as you look at the front of the table) I cut a square hole to place the sewing machine in. I hung a panel of plywood below with carriage bolts and nuts with washers to support the bottom of the machine. As such, the sewing machine plate sits flat with the top of the table. The table sits a bit high (I am 6'1" tall) but works out nicely for me.
I then took black plastic garbage bags and taped them with duct tape to the table top. The fabric now slides nicely across the table top. You'll see how important this is. Wax the top of the sewing machine also.
I then put my ironing board behind my shoulder lengthwise a couple of inches above my shoulder height. This helps control the roll of fabric as you feed it through the machine.
If all your lines are pretty much straight, use a walking foot. You will see how you can control any amount of tendency for the fabric to scrunch up and overlap where you cross other diagonal or intersecting lines.
I hope some of these ideas help you.
