How many grams of carbohydrates can be stored as
glycogen in the muscle and liver? I tried searching
for a max amount in grams and came up with
one figure, ~600 grams. I'm sure it probably
also varies from person to person. An endurance
athlete probably conditions their body to
have a glycogen storage increase. But I'm just
guessing at that one(Based on the idea that
an endurance athelete gains an increase in
mitochondria in muscle tissue).

Approximately of course. The liver can store 100g (100 x 4=400
kcal) and the muscles can store up to 400g (400 x 4 = 1600
kcal). Total 500g in liver and muscle. Therefore the body can
store up to 2000 kcal of gycogen.

A well trained athlete will use less glycogen.

Which is about correct, and accounts for about 20 of the 26 miles of a
marathon.
Proly the elite are able to make up the diff w/ adaptation, carb loading,
mebbe some real high blood sugar, and mebbe soft drinks along the way.
The paltry 100 gm of liver glyc is why some biochemists claim that we are in
mild ketogenesis by morning, w/ muscle catabolism already ocurring, to
supply the brain w/ glucose.
The mere thought of this must give BBers the willies.
There are arguments against this, tho, but the overall principle is correct.
Just not sure if it indeed happens within 8 hours.

Wish i knew.

I think that depends on factors such as muscle volume, wether or not you do
some higher rep work, androgen and insuline levels.
