kushina was blushing and hanging her head (a typical pose from a shy person) when she made her debut (in jiraiya's flashbacks), so thats why they thought she was similar to kushina...

it's hard to say... Someone has made me to notice that Kakashi said the same word (Daisuki) with his subordinates only a few chapters ago.... Daisuki is also used for platonic love, but since it is used by a female towards a male, I wouldn't have doubts... But it is not that she wants him to be hers.... As kakashi said, She only wants to save him and that's all. It's hard to say.
He also used Aikittene to describing Sakura's love for him... It's very strong... anyway it's kinda weird when a third person uses a such word for describing others' love....
Im sure that Sakura feels romantic love towards him but I am also sure that she doesn't want to be enganged with him... she herself said that she cannot to do for him. SS isn't decided by the destiny.
