I would make sure you contact your school OT right away. I say this because it sounds as if maybe your daughter will qualify for OT services through your school district. (These issues are interfering with her daily life and will soon interfere with her education if she doesn't get help)
If your district says the OT is out for the summer, ask about talking with the principal about some transition issues.
Good luck...hope you can find some help to transition smoothly.
I would also call the district. During the summer, our district often is working on computers and so e-mail isn't always running. Also, the way districts work there is going to be an intensive testing period and there is a chance nothing will happen the first week or two as your daughter is "adjusting" and getting used to Kdg., during this time the Special Ed. Department may be observing and dealing with other kids too.
I think the best thing for you would be to get into some private OT sessions. This will give you a head start. Have you read the book "Sensational Kids?" It is by and far my favorite SPD book. It may give you some ideas. The other reason I recommend private therapy is because school focusses on "educational therapy." Some schools may not even recognize SPD and may think this is a behavior issue (NOT). However, you want to get a head start so the transition to Kindergarten is smooth.
As far as ideas, does your daughter crave input in other ways? (Running, bouncing, jumping, tumbling) You may want to try some of these ideas and see if that helps. For example, "Before we put on the panties, I want you to do 3 summersaults across the floor. Then, jump into them!" You have to get everything into a state of balance before she can even think about doing this.
You may also want to try having a weighted blanket or vest for her, some kids find these very relaxing and comforting. (Basically, a HEAVY blanket or a vest with beans or beanbags sewn is)
Good Luck, try and keep the battle to a minimum and remember this is out of her control. She needs you to help her through it. (Breathe, breathe, breathe)
