Most of the time I'm in a PA-12, my flying buddy is up front - He's a foot taller than me, so I fully sympathize with your inability to see the panel! I end up using my peripheral vision a lot more to help keep myself straight and level, much less learning when and how much to flare.
When you taxi (and take off and land) in a tail wheel, I can still quote by heart, "Small smooth corrections, not large late ones!" Each time you touch the rudders, you are moving a big huge control surface out there on the back (and a steerable tail wheel, if you have one). Just like you don't spin your steering wheel hard to the right and hold it if you've drifted a little in your highway lane, you don't jam your foot down and hold in rudder for small corrections. Think like a boxer's fists - jab, jab, jab. In slow motion, what you are doing is putting in a small correction, seeing where the momentum from that correction takes you, then putting in a refinement or another small correction.
When you have a long stretch, you'll learn to do S-turns on the taxiway, so you can get a good look at any traffic or hazards up front. GO SLOW. The old adage that a taxi should be no faster than a man can walk often gets blown off in nosewheels, but it's like driving this way: the faster you go, the faster things go wrong and the easier it is to overcorrect.
If your instructor is amenable, I highly recommend doing a low pass, flying the airplane one wing-length above the runway for its entire length. The sight picture and the attitude for landing are critical, yet you only experience them for a few seconds each flight. Doing this will give you a much better feel for the sight picture you want, and handling the airplane in ground effect.
If you have time, find a book named "Stick and Rudder" by Wolfgang Langewiesche, and "The Compleat Taildragger Pilot" by Harvey Plourde. They thoroughly cover this sort of flying, with lots more advice and experience than I have!
