Airline from Singapore:
Tiger Air and Jetstar
Travel Visa - Allow at least 4-6 weeks
1) Get from the embassy
2) Visa on Arrival
Use the online agent on www.Vietnam-Visa.com
Money Exchange:
There are several money exchange counters right when you arrive at the airport. The rate is usually better than Singapore.
Taxi:
Between airport and District 1 is about VND 120,000. Don't take the "taxi shuttles" or any unofficial taxi or vans, they are more expensive!
There are many van taxis in HCM and may take up to 7 passengers.
Accommodation:
For a big group, 5-7, it's recommended to try the Sommerset Serviced Apartment:
