I would assume your class had a list of supplies needed. If not, I'd say start with a rotary cutter, ruler and mat. Look for simple block patterns on the internet to practice.
As for sewing machine attachments, a 1/4" foot is a great tool. Of course you don't have to have any fancy attachments. There are ways around all of it.
I don't like hand work except embroidery, but there are many, many things quilters can carry as hand projects. English paper piecing is very popular with some quilters.
Start small. Don't spend more than you are comfortable with. Many beautiful quilts were made long before all the fancy gadgets. Get a feel for how you like quilting and add tools as needed.
