Looks like a great table! I have a small ikea computer desk that I use for both quilting and cutting. I use to use the back of an old painting on my bed to iron/press. I've upgraded to a cheap ironing board but sometimes you just have to make it work!
When you look at patterns I would actually recommend you not try that "beginner" quilt on page 3 right now. It's a sampler and you have to learn A LOT on each block and they are more complicated then you might think, I would have gotten very frustrated and quit if a sampler was my first quilt. And any quilt that has triangles, run away!!! I would recommend a simple quilt where it's mostly one block. As you make each block you will become more and more confident in your sewing. I would recommend one of the two following videos as they are more simple and have a full video on how to make the top. They are both jelly roll quilts so you can use your fabric rather than needing to buy some more. And Also, when learning to piece accurately, if you pick fabric that is more busy, or lots of similar colours you can hide mismatched points better as you are learning, ask me how I know lol
I'd also recommend making half the size to make it less overwhelming.

Go easy on yourself and try to have fun! For what it's worth I have never washed/dried any fabric and have great success in my quilts.
