Earlgrey, tbh I would start by ditching the television in the morning before school.
We don't get a good enough reception to have tv, but we do watch videos and dvds, and one of our non-negotiable rules is no TV(vids or dvds) on school mornings.
Dd(7) gets up at 7.30. She usually reads a book or comic for 15 mins then she has breakfast.
Then she gets dressed in the clothes we've put out the night before(if we're organised , otherwise it's a matter of unearthing them from her pig-sty of a room (just one of the things we need to make headway on)).
I think you need to decide on a routine/timetable that is acceptable to you, discuss it with your dds (talk about it today, then go over it again with them tomorrow so that you're not springing it on them on Monday (or Tuesday if they have a days holiday)), then implement it.
Stay calm. If they're late they're late. Do not get into a shouting match with them. Just state how things are to be.
Just an thought, but could you involve dd1 in the process of washing/laying out her clothes, or even letting her pick a new set of clothes (depends on how strict her uniform is. We have lots of leeway - as long as its a white top, grey/black skirt/trousers/pinafore and the correct coloured sweatshirt/cardi/jumper).
Try not to dictate, but involve her, give her some responsibility, ask for her help, and look upon it as a challenge for both of you, something that you're in together, rather than it being a battle between you.
At the end of the day if she absolutely won't cooperate, then how about saying "Fine. No problem"
"If you want your uniform washed every night, then fine, no problem, but you're going to have to do it yourself."
"You're going to have to take it off as soon as you get home, wash it, then put it to dry overnight"
"You're going to have to get up early to put it in the freezer"
She should be capable of this at the age of eight.
Sorry for rambling, but have been thinking about this since yesterday after my initial flippant post.
