Re-entrering Thailand With A Tourist Visa

hi friends

we live (two, indian natioanlity) in korea and are relocating back to bangalore india. on the way back we wish to travel in thailand and cambodia.

since it is relocation we have large baggages. 2 big and 2 cabin.

please help me by answering the following questions.

1. if we get a transit/tourist VISA on arrival to enter thailand for a week, can we travel to cambodia in between for two days and come back to thailand again?

2. can i check-in my two big bags directly to banaglore despite a week's gap?

3. how much time does it take to obtain VISA on arrival? and what are the necessary documents required for a couple?

regards
