OMG!!! What in the world sorts of questions are these, anyway???! It's taken me THIS long to put together what I am about to post, only to find out upon reading the original poster's questions that I haven't formally answered all the questions, though some of it's there. What in the
world?!

I'll come back occassionally and edit this post, perhaps. I've had thousands (maybe literally) of "smaller" thoughts and adjustments over the years, but here is a start on some of the bigger ones for now:
1999-2002 > University
* First time in whole life to seriously practice everyday
* Hugely inspired
* Developed enormous anxiety over the past, present, future
* No formal idea on posture
* No technical routine
* Didn't know chords, scales, arpeggios
* Began w/scales, then on to chords and arpeggios for a few months in senior year for recital prep.
* Had no idea what technique meant = no particular focus in "technical routine" -- always felt lost and out of place = fed anxiety
*Started developing practice strategies -- didn't know which direction to go, didn't really understand what was helpful and what was not, nor where anything in particular led. No perspective on progress or not.
*Some Czernys -- no sense of direction with these
*Specific way to practice/use pedalling
During this time, my instincts always told me that something didn't feel right fundamentally, it always always felt like something was missing no matter how I played (and if I ever did do something well, it felt like an accident or as though I cheated death or something ... heh). Doing things well by accident or by the skin of my teeth didn't feel fulfilling to me, partly because there wasn't anything for me to link the success to, most of the time. I had no real idea on why something would go well and why it wouldn't (though, I can look back now and have some answers). It's literally as though I felt like I was missing something to stand on (yes, my technical foundation) and I think this really fed my anxiety about everything at the time.
2002 > Recital -- completely blew my whole world -- not just my mind-- as I knew it.
02-03 > Developed HUGE list of music to study with absolutely no idea how to go about learning all of it, and therefore ANY of it. Completely overwhelmed.
03-04 > Life-altering personal experience = No practice nor lessons nor singing for months.
2004 > Found forum and read as much as possible
* Special focus on teaching and practice strategies -- still overwhelmed and anxious, lost, depressed, irregular and hazy practicing.
2005-2008
*Improv.
*"Finger Independence"
*Posture, balanced and centered seating/sitting on bench
*Joint alignment over key alignment
*Forearm rotations -- complete obsession and transformation of entire technique
>Disconnect with music and repertoire
*Circular motions and patterns -- clockwise and counterclockwise motions
*Angles and lines at on the keys ... efficient motions/paths
*Starting to know what "Full arm" means
*More bodily awareness -- starting to consciously discern tension vs. relaxation
-- starting to reverse physical affects of huge anxiety from before, still not feeling connected with the music, repertoire; my own personal musical desires starting to seem very, very far away and out of reach.
2008-2009
*Intro to "Pianistic Motions" as tied to musical text
*Special emphasis on dexterity and new sense of "finger independence" and articulate sound
*How to strike key and then immediately release/relax muscles
*Lift-play-release -- obsessive focus
*Same sound, no lift then same strategy on staccato
*2 main Czernys w/specific direction
*start on serious rep. again since years
*re-alignment with the keys, but this time without tension
*supple wrist w/articulate sound -- articulate sound without unnecessary tension
*Complete reworking of general technique OUT of all forearm rotations and non-key alignment
2009-2010
*Focus on rep. w/pianistic motions
*New expectations in accuracy
*Scale work
*Octave Czerny etude and one other Czerny w/ specific direction
2010-2011
*five-finger patterns in Major and minor covering the entire keyboard
*Scales, chords, arpeggios
*New "fundamentals routine"
*"gesture" in motion
*Carryover of Bel Canto physical technique
*awareness of ribs leading to sound
*Using core muscles
*weight distribution
*new awareness of back, legs, and feet
*further awareness of arm usage/position
*further awareness of hand positions, finger balance, joint and key alignment
*entire bodily involvement, from toes to head
*new practice strategies and confirming practice strategies
*Developing new perspective on shapes, angles, lines, motions, sound, listening
*focus on rep. and fundamentals routine
*connection with entire keyboard at once -- connection with voice
Also, I've been singing the entire time I've listed here and have carried over ideas from that, and progressively moreso in the past few years, especially.
