Прошу, кто владеет английским, переведите пожалуйста с русского!!! (предложения внутри)

1. "Good thing you know such a lot of languages!
How long you`ve been learning them? Was it difficult?
Would you like to learn russian as well?)
P.S. Tell me,please, something interesting about your town!"

2. I`ll be really glad! Come to St.-Petersburg and I`m gonna show you all beauty of our city!

3. I cash you - How it`s supposed to be translated? The translator does it kinda strange.
I congratulate you too and your family! Happy New Year!

P,S, Так как общение довольно неформальное и дружеское - соответственно и перевод.
