I'm gonna give you a couple of links here that may help you a bit.
You can measure from the ground to the bottom of the rocker panel to see if you have any lift, the stock ride height is 18" so anything over that will be the amount of lift. There's more here, YJ Stock Specs.
Take a look at your springs, if they're not flat or near too it, they're gonna be lift springs.
As for the shocks maybe this write up from Joe Dillard can help you a bit.... Everything you need to know about shocks
And finally help with posting pictures.... How to post pictures
Hopefully that will at least get you started in the right direction.
