#3. boots...get were I'm going ?
You don't need high end boots yet. When we find where you live and plan to ski, we should be able to direct you a good shop.
After a couple of times in rental boots, I took my GF to my boot fitter. He spent 2 hours with her getting her into the right boot. She had 3 brands he had her try on. The fitting process is pretty involved. Wear old shoes, so the fitter can look at the souls, he'll inspect your feet and ankles, check your flexability, have you stand, to check alignment, talk to you about your skiing (or in your case, lack there of)
and recommend a few boots.
I gather your serious so you might as well start in a decent boot, the shop may have some leftover boots from last year at a discount. I spent $250 on the GF's boots, they were current year boots. Her Atomics have lots of adjustments and for two years now she has not had any hot spots in the boots.
You want a boot with about a 80 or 90 flex at your level.
She also wears a thin ski sock. I have started her out in Smartwool ultra thin socks. The idea is you want as thin a sock as possible so that when you move your toes and foot in a good fitting boot that movement is transfered to the ski at the same time.
When you get good and have great fitting boots, its amazing that you can think turn and the ski responds, when I have the ski up on edge in a highspeed arc, I can press down with my big toe and feel the arc of the turn tighten up.
