I will happily try to explain, however first recommendation is to get a beginners book at library or local bookstore. It can be found in gaming area, card games etc.
There are so many bets on the craps table that are way favored for the house advantage.
To answer your questions:
First of all when you walk up to table, there should be a sign posted under the rail, on inside of table usually just under where the "dealers" stand -the casino staff on either side of person sitting down (the boxman.)
This sign will tell you the minimum bet, and what odds you are able to place. From what I read on posted here on cruisemates, most cruise casinos have double odds.
In general this means "double" your original bet that you placed lets say on the passline ( I won't even explain don't pass odds very confusing)
The "odds" bet is the truest and most favorable bet for the player. If one were to bet, always play the max one is allowed and can afford behind the line. I can instantly tell a "new, or don't know how to maximize your odds" when someone throws a bet on passline, takes no odds or worse yet a huge passline and little odds.
To get chips for paper money lay it out, and as placing it say "change, or change only only" --this lets them know you want chips and not placing a bet!
. Be courteous and wait for a lull or see dealer has paid bets off before throwing money in--their first responsibility is payoffs then
I will give you an example how bets are paid off.
Say you placed $5 on pass line and double odds behind it once the point was established. Say it was a 4. This is a harder number to hit before a 7 and so a 4 or 10 is paid at 2 to 1. So pass line is paid $5, while the odds bet of $10 is paid $20 so you risked 5 in front, 10 behind and won $5 + $20. The 5 & 9 are paid at 3:2, and 6 & 8 paid at 6:5 accordingly.
Most bets say are minimum table amount (come,field,place etc.) the middle of the table or call, horn bets are usually $1 minimum as they are more of hunch bets and odds are against the player at an average of %11 range. Although they are a real rush to bet a $1 and get paid odds at 10:1 or higher--for the thrill of the bet, not the logic of the bet! Hope this helps, I can add more as you post questions.
#1--GET A BOOK and read up--just basics help, I am also sure casino will have free lesson times.
