Please allow me to offer some opinions (armchair speculation, based solely on my own experience)

Quoted message said:The problem so far is that I really feel the impact from hitting the ground. (granted I've been
running on the sidewalk and in athletic not running shoes, which I don't have yet)
Running shoes might help you go a little further without any change in form.
I know of runners who have ignored form and permanently damaged their knees.
Or, try every other run on grass. If you dribble a ball, soccer style, arround a grassy field for a
while, you develop the support muscles needed to survive on pavement. Accelerate between kicks by
pumping the knees to develop a strong running leg.
If your present shoes have plenty of room, or, you can use thinner socks, adding a flat neoprene
Spenco layer under your insoles can increase cushioning.

hard not to move that much vertically when I run.
Think horizontal.
Since you are taller, your optimum stride rate may be less than 180/min. I can demonstrate smooth
nonbouncy quiet running at almost any reasonable stride rate, with any type of foot plant and in
"any" type of shoe. I bet if you tried some drills to run quietly, you could find a way to reduce
the bounce. In order to do this you have to involve your quadriceps muscles more, for starters.
Running with too little knee flex, as if on sticks, could be counterproductive.
Your legs "know" that the surface will not give and may be reluctant to relax. Some drills to try:
short faster running accelerations on grass or sand, running with a lower center of gravity using
more knee bend, hill climbing, bounding, etc. Warming up by cycling, doing one-legged short-arc
squats, lunges, or step-downs on a staircase, may help recruit the quads. Running uphill can help,
as long as you are careful not to run downhill. Training yourself to run downhill without "bouncing"
is the ultimate test. Even hiking hills could be great training for this.

Quoted message said:So I was doing some reading on techniques on the web, and most of them say that you should be
hitting the ground first on the ball of your foot. But the American Council of Exercise says to
hit heel first: acefitness.orgfitfacts display.cfmOpen ↗
Strictly speaking, you do neither. What happens is that the outside of the heel touches lightly,
then your foot rolls forward and inward like someone rolling to cushion a fall, then your heel
lifts off the ground, then you push off with your toe. The front of your foot absorbs most of the
impact even when your heel touches first.
I like this explanation. If you pick up the pace enough, you might find the initial contact point
moving further forward on the foot. If you "reach" forward by overextending your knee in order to
cover more ground, you may overstride. Rather, push off more effectively from behind to move
yourself more horizontally and less vertically. Some runners do train themselves to run at 180
cadence and to use a forefootstrike, in order to improve and protect themselves.

Quoted message said:So maybe this has been discussed before and its one of those personal preference issues, but the
ball arguments seem to make sense. What would be the advantages of landing heel-first instead?
Do whatever is most comfortable, but try not to overstride. This increases the amount of impact.
The advantage of "landing heel first" (not really an accurate description of what happens) is that
some people are too heavy or not strong enough to run like an elite miler, and trying to force
them to adopt such a running style is likely to produce injury.
Makes sense.
It is better to work

technique

Perhaps, study a model of how you want to look. For example, record coverage of a Kenyan or
Ethiopian female marathoner. Then convert this visual input and imagine how it would feel. On your
next session, preferrably on a track, treadmill or grass, try exaggerating this form in short
spurts. Doing drills such as short-arc lunges or hill climbing can help your muscles adapt.
