A economic alternative to a lift kit is a spring over conversion, where the axles ride under the springs instead of on top. This will get you 4 of lift or so.
Just remember to correct you drive shaft angles and check your brake hose length, also the jeep will not handle as before. You will also probably want/need new spring shackle bushings.
If you opt for larger wheels/tires keep in mind that this will further lower your effective gear ratio. If you intend to seriously off road, the first thing to consider is a decent cage, the CJs short wheel base, narrow track, and relative high center of gravity can exacerbate some situations to a critical point
Have fun, be safe, and congratulations on the your find.
Life is no joke but funny things happen
