get yourself a bigger trolley jack and axle stands to start with, you will need them if you do any work later on
if you soak everything beforehand you could be lucky, also loosen the bolt a few turns, then soak with penetrating fluid and do it up then fully off. Rear shocks have 2 small bolts high up, soak the back of the bolts as much as you can and use lots of extension sockets to get a decent pull. If you snap one then drill out and either tap or go bolt and nut.
front shocks and springs easy, just watch what your doing with the spring compressors and remember you can get more movement oft the axle by disconecting tha sway bar.
Thats about it, oh and always use 6 sided sockets to avoid misery
good luck
