I used Pages when I had my first generation Ipad with no problems at all....Might be worth a complete restore from iTunes...That should sort it out...If it doesn't then you might have a hardware issue...My ipad 1 went to a buddy a long time back, and he uses Pages all the time.
No, not unless all your stuff is in the cloud, and it won't work across borders anyway....You could try removing pages and reinstalling it.. ( oh, no you can't, unless you can access your account)
Might have to wait to restore when you and Mac are reunited.
