Congrats!! Like so many others, I love mine. I have 4 .... will probably get more if they come available for a good price. I use them almost exclusively for piecing. And, I've done some FMQ and walking foot quilting for small items.
I have found attachments in various places.... often unexpected so don't worry about that. They tend to pop up. I did buy a 1/4" foot and a walking foot that I use often.
I can't wait to see your FWs coming out party...... make sure and post a photo for us all to oogle over!!
