Yes, you should take her to the vet. She could very well have an eye infection and that is not something you want to mess around with. Their eyes are precious. If it is an eye infection, they will more than likely give you eye drops that are like an antibiotic. Good luck!
I almost forgot:
As far as her bowels being soft, mention it to the vet. If it is a one-time thing, then it is nothing to worry about. However, it could reoccur and there could be something else going on with her. She's very tiny, so you have to be very careful with her.
