ILP is different from one RO to the next, you are being to reasonable based on the fact you were denied a education that would have cost the VA thousands per year.
You like to cook....ask for cooking classes, or you kitchen redone with the latest appliances.
A computer is good, along with Graphic design classes.....But you could do this yourself.
A good orthopedic mattress is good.......but you could get this yourself.
Painted walls are ok, But again you could get this done on your own.
Bottom line here is, focus on the item that is most important to you. I to went down this road and let the VA off with a 2K computer....dont get me wrong, it was needed and I did not do my homework on this ILP before hand , so I took what was offered.
There was a CVA case on here some time ago where the Vet liked to paint, or photography......the VA was happy to provide the paint materials and some classes.........the vet also wanted a enclosed glass addition so he could paint......The VA said hell no it would cost 30k....CVA said hell yes and the VA had to build it.
It never hurts to ask for what you want, you can always appeal......but stay focused on the thing you realy cant afford but will in your opinion help you the most.......some say you only get one shot at this, I dont know the answer yet, but I will be testing the waters again in the future.
