hi,you can take a bus to Siem Reap from Saigon, transfering in Phnom Penh, that's all it works. it's a lot more cheaper than by air.
if you are Chinese, you have to apply for a visa to Vietnam before you leave, but it's not necessary for Cambodia, e-visa works everywhere. search on taobao . around 300-500RMB per person.
Saigon is more of a transfer city, you go to many places from here, you can visit the central postoffice, the palace, take part in meikong river one day tour, or just enjoy the city and life of Vietnam people. Most people live on Pham Ngu Lao. check out booking.com, the hotels are really cheap. hope it helps you.
