[Repeaters]

So I’m new to GMRS and need someone to explain how to connect to a repeater? I have a Rugged hand held and would like to buy a better one for my truck.  I got a license and used MYGMRS.com to find the closest repeater.  I received permission from the owner as well.  How do I know what channel, frequency and the other tones? And how do I program that assuming I’m in range?  
 

Thanks,

I’m sure I’m going to get a lot of crap but I’m new and I am trying to figure out how to program my radio to a repeater.   I watched several videos and still am a bit confused.  I have a hand held Rugged Radio but would like to get a better one for my truck. I found the closest repeater to me by using myGMRS.com and got permission with the owners of several different locations. My question is how do I know what channel, frequency, and what tones? I’m not sure how that all works.  Any help would be appreciated.  
 

Thanks.
