Buenos dias a todos.

I am going to Chile in a couple weeks and I'll be staying at my fiance's mother's house. I haven't met her yet, and she speaks very little English, if any. I was hoping to get some help with translating some useful phrases/questions that would be helpful during my stay...
Could someone tell me how you would say, or of similar context:
-It's so nice to finally meet you!
-I am told you're an artist, may I see some of your work?
-Is there anything I can help you with?
-Thank you for raising such a wonderful person... (awe)
Um..now I'm really nervous and I can't think of anything so say to her...lol
Oh my....any ideas?
Thanks so much.
