I really need help

my girls are about to turn 4 and 5 next month and then it's Xmas after that and I'm pretty much clueless!
They're having innotabs/leappads for Xmas, which will be their main presents, probably only with a few stocking fillers/crafty bits or something, but birthdays are proving tricky!
The big one wants princess stuff, she's having a princess theme party, so I was thinking of getting her a sleeping beauty dress with accessories to wear to it (her favourite) and she's mentioned she wants the DVD, so will get that too. But in terms of a "big" present, I'm clueless! Would a 5yo appreciate a magazine subscription? She really needs some new toys, but She just doesn't seem interested, she'd rather watch tv dressed as a bloody princess

I'm on the lookout for some nice easy-reader type books too, cos she's just started reading and loves being able to read to herself!
The small one's a flipping nightmare! Apparently she wants a toy version of her Aunty, so she can kiss it and tell it how much she loves it

but that's all she wants! Everything she's had recently, has been broken, chewed, drawn on, you name it. So I'm totally stuck cos I just don't want to get things that'll be broken! She's a proper tomboy too, so loves all active stuff, but it's kinda the wrong season for outside things!
Help?!
