Hi Halla,
My advice is that you should try to negotiate with them to have them pay all your utilies including the internet. For where i worked, i just had to pay for my electricity and phone bill. For a teaching job in Beijing, i would think that they would offer better deals for teachers to teacher there!

so again, negotiate first b/c i really think you can get better deals that what they offered, and as for the plane tickets, make sure that you request that you buy the plane tickets and not them, only have them reimburse you the money! please keep that in mind, i myself had the problem with my plane ticket when i was teaching in China...So make sure you state that YOU'LL buy the plane ticket and not them!
