Good old fashioned paper travel guide will help you too! Even a quick Google check will give you some hints on what to see and do. If you do not have a laptop or desktop computer borrow some time on one or visit an internet shop for your research. Maybe just make some copies of the appropriate information that interests you.
If your time is short in these countries put a priority on what you really want to see and do that first. Know what your visa requirements are for the passport you enter with. Also DO NOT leave these two countries with their currency, no one else wants to change it later on. USD usually work in these two countries too but you will need their currency for cheap purchases. (Google check "what currency" for Vietnam and Cambodia.)
From this forum:
For first time visit to these countries my advice is to avoid any flights that arrive during the middle of the night. It is easier to book hotels and plan your visit when you arrive during the day or early evening.
Buy a guide book. Vietnam & Cambodia are covered very well.
