Welcome, I started out on kitchen table but now my kids have flew the coop I took over 1 bed room & DH took over the other for an office. So far you have done good on the basics. If you plan on quilting your own a walking foot would help. I hate to say this but a seam ripper is a must. There are alot of tools out there & sometimes they're just good to look at & not much use. For staying organized I would purchase plastic drawers on wheels, Walmart has them. Then as you grow or change your mine it will be easy to move. At one time I put a board & pad on mine and use it to pressed my blocks on. You can also move it beside you when you sew and use the top for extra space for pins ect. I got mine from Walmart.
This is a great Board they are very helpful. Keep us posted on how you are doing.
