Thanks for thinking of us as experts =D
1. You don't get a new rod, you can get a new lure, the frog lure, to get this you must complete all the levels of the ROLLAGOAL (spelling?) minigame (up to 1-8) which is located in the lure fishing area on a shelf which you must look at (using C button)
You can also get the sinker lure for your rod you get at the start of the game, to do this you must catch a bass, catfish and pike while fishing in the lure fishing area (it will cost 20 rupees to do so) then fish (bobber) in the south west area to get the Sinker Lure.
2. The lure fishing place is located in Upper Zora's river, it's easiest to get to once you have done the first three temples and got the master sword/control of wolf transformation because you can warp there as a wolf and then change into a human and enter.
