Visiting Guangzhou for 6 days 5 nights

Hi,
I am from Singapore. Will be visiting GZ for 6 days alone and this is my first visit to China. I can only speak English and I intent to stay somewhere near to Huaisheng mosque vicinity and few other places. I wonder if you could advise me on few things:
1. Should I take a cab or train to Huaisheng Mosque area? How much will the cab fares be? If taking train is not a hassle, I be glad to take a ride.
2. recommended Inn or budget hotel to stay near the Huasheng mosque.
3. Do airport staff can guide me by speaking English?

Just give your best advice cause I know it is not easy for beginner like me. I do appreciate all the advice given. Thanks!!
