Firstly you shouldnt concern yourself about paddling to the line-up just yet. rather get popping up right on the whitewater/foamies. As far as how long it will atke to stand up confidently this is xtremelly unpredictable as some people stand up straight away whilst others take much mmuch longer. If you take much much longer dont feel bad about this it just means your body is taking longer to find ts balance it does not mean that you will be a worse surfer in the long run. (always remember that)
Everyone is different with me i was standing up on the first wave literally but then i expected this as years of bodyboarding dropknee had implanted the pop-up motion in my head. It took me a week before i was standing up confidently and about another week before i was actually riding proper waves.
It also has to do with how much wave experience you get i live by the beach so i go in everyday which = a lot of experience.
This goofy/regular problem is not uncommen i had the added problem because when i used to BB i would use either or. The best method to test what you are is to descide what your power leg is i.e the one you would throw a roundhouse kick with. If that happens to be your right foot then you can be pretty shure you are regular (there are exceptions) When i started i found it much much easier to pop-up goofy but im actually regular footed the reason why this happens if because your power leg is the clever leg and can adapt itself easier. Also imagine yourself really carving up a wave doing cutbacks etc and then imagine your foot position.
You should not concern yourself with getting good quick if anything this leads to frustration so just take it one step at a time and build your experience thats the bst way to create a solid foundation from the floor up
Have fun
but still love every second of being in the water and falling off my board.
