As wizard says both these jobs are easy.
I did my body lift in a couple of hours on a Sunday afternoon. You should replace all 5 flexi hoses but in reality the rear one does not have to be done. I've not done mine and I've driven some pretty extreme lanes and I still have brakes! The brake hoses is actually the worst part of the whole job. Especially if they are anything like mine and required removing the the angle grinder spanner and new brake pipes also.
Here is a guide I wrote -

1) If you buy a kit from Wizard you get special extensions for the radiator (which saves moving the brackets and drilling new holes - although actually moving the brackets helps with relocating the PAS reservoir) but most importantly you get specially made floor spacers for the rear boot floor which require no welding. Just drill a hole and bolt them on. Much better than getting 2" box section and welding in place!
2) As far as the bumpers go - be warned you will need to cut a notch out of the end caps to allow the body to rise at the back and you will have to remove the plastic cover on the rear cross member and then having done that you will probably need to weld patches on all the big rust holes that the plastic cover has been covering up.
The steering will need moving on the splines. No big deal.
You will have to put some of the bolts in the wrong way up but this does not matter.
You also will need to so some relocation work, if you use Wizard's extenders, with the PAS reservoir or the pipe is under too much stress and pulls off and you get PAS fluid all over the floor! Ask me how I know!
The diff lock lever does drop down a bit and this is a bit of a PITA. I tried the lever extension but it did not work for me (what it needs for the extension to work is to bend the lever forward. I did not fancy the idea of this as I was afraid it might break something so wimped out in the end and left it as is. I ended up just cutting about 10MM off the bottom of the knob so it did not foul against the gaiter and the center console.
Cutting the arches is also easy -
http://rangie.com/articles_topic.php?id=364&cat=3&subCat=6The worst bit is re-shaping the rear doors. You should make sure you get a proper aluminum cutting disk for your grinder. You will get flaking off of the paint at the bend (or worst if its had a skim of body filler!). But just touch it up (it is a working 4x4 after all).
I am a big fan of the body lift as you don't alter your steering geometry requiring castor correction arms and prop UJ correction spacers.
