I am installing a 96,000 BTU woodstove and am wondering how high above the roof line should the chimney extend..I have heard 2 to 3 feet for proper draft...

it depends where you are (code-wise). in california, 2 feet above the highest peak of the roof. three feet would probably guarantee no problems.

The 2'-3'-10' rule is right. It meets the International Residential Code. 3" at roofline and 2' higher than any
combustible material within 10'. This meets the code for
clearances but , the code is just that-protection from
combustible materials.
Your draft depends on open space around chimney and
surrounding buildings,hills ect.,Your best bet is to check
out any chimneys in your immediate area and see there
set-up or ask your neighbors if there's work alright,Or a
local mason who does that work.
Almost ever state building code and fire code now require
spark arrestors on top of chimney. Remember that you
cannot install a wood burning stove in a chimney/flue
that also serves any fuel burning appliance. Good Luck

Every house in our city has a chimney (heating system with gas or oil, at the edge of Zone 4 and 5). I always see chimneys within 2 to 3 feet (and rarely 4 feet). It may be a compromise between good draft and aesthetic.

2 Feet is usually good. But, believe it or not codes has a say on this. If you're in an area that doesn't dictate 2 Feet allows proper drafting. If you go higher no big deal, less soot on the roof.

Most building codes require the chimney extend two feet higher than anything within ten feet horizontally.

There is a rule for this (it's called the 2-3-10 rule). It needs to be at least 3' high and 2' taller than anything within 10' of it.

Well here is the baseline formula for figuring chimnet draft or draught. I would also check local building codes for other requirements
