Here arb states you want a snatch strap that is 2-3 times the Gross Vehicle Weight (GVW) of the lesser vehicle.
For a Jeep that makes a snatch strap that is 17,500 ideal. 20,000 are much more common and cheap and should work great. The whole idea is to have some give that will help ease stress, and give a bit of a sling shot effect. If you get too high of a rated snatch strap you loose the benefits. Check out this video.
A chain, tree saver, or tow strap have no give. They are much more likely to break something if used as a recovery option. No recovery/snatch strap will come with hooks. Besides that they are hard to tell apart. Some toe straps dont have hooks and look about identical to a recovery strap. If your rigging up a snatch block you would want to use one of the no stretch options. A snatch strap can work in a pinch for towing. It seems to me like your better off with an extra recovery strap vs a toe strap. Maybe get a 20' and a 30'.
SNATCH STRAP SIDE NOTES
It's worth noting that you should never use a ball hitch to recover from. With a sudden impact they can, and have, flung off and killed people. It's also worth noting that you should take as much twist out of the line as possible before a pull. Besides that its just common sense to use as much speed as needed but as little as possible.
I think with shovels the bigger the better. A 5' one would take care of business if you were high centered in goop. One with a point will be easier to shovel dirt with. There are also army folding shovels that can be use as a hoe.
The lift-mate seems like the best possible accessory for the hi-lift if your hi centered. Then you don't have to also lift up the suspension like you would going off a rock-rail or bumper.
You'll want to have some WD40 for the hi-lift.
You didn't put a Pul-Pal on your list. It is a nice addition for a winch. It's basically an anchor if there isn't a good deadman spot around. They are not super cheap, and I wouldn't doubt they are pretty heavy. Smittybuilt makes one. I think they call it the wasp.
