Welcome from Ontario, Canada. If you are just quilting straight lines, you can just use your regular foot and increase your stitch length a bit because the thread is going through the quilt sandwich. A walking foot is helpful so that might be something you want to buy in the future.
A well basted sandwich will make your quilting easier. You can use 505 basting spray if you have it, safety pin or needle and thread basting. 80/20 batt is easier in my opinion to quilt with then polyester.
