Answer

Well, you wouldn't say 'stair climbing' you would say 'climbing the stairs'. There's...
climbing the stairs (emphasizes the height of the stairs, they're so many it's as if you are climbing up a hill)
going up the stairs
ascending the stairs

The opposites would be...
going down the stairs
descending the stairs

Answer

If you're clumsy, the answer is "falling down the stairs."

Answer

climbing (up) the stairs
climbing down the stairs

Answer

Ascending the stairs / Descending the stairs.

"Stair climbing" sounds a little funny. I'd use "climbing the stairs".
