It's pretty easy to do all you want.

How to make a file path to your applications document directory:

NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* plistpath = [[paths objectAtIndex:0] stringByAppendingPathComponent: @"myplist.plist"];

How to read it in:

NSDictionary *dictionary;
dictionary = [NSDictionary dictionaryWithContentsOfFile:plistpath];
NSArray* array1 = [dictonary objectForKey: @"array1"];
NSArray* array2 = [dictonary objectForKey: @"array2"];
... etc ...

How to write it out:

NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] init];
[dictionary setObject:array1 forKey:@"array1"];
[dictionary setObject:array2 forKey:@"array2"];
... etc ...
[dictionary writeToFile:plistPath atomically:NO];
