I have 2 sets of jack stands, 3 tons for under the back axle where they don't need as much reach and 6 tons for under the front frame, they go tall so i can get all wheels off the ground for rotating tires, hard to do with bigger tires and ifs
floor jack I'd look for one that is at least 3 ton and the higher it lifts the better, otherwise you need to stack a wood block in between the jack plate and the truck to get it to get the tires off the ground, kinda sketchy
a creeper dolly for sliding around under the truck is a must if you have smooth concrete, if you're trying to work in gravel, you're stuck with a piece of cardboard. I like the craftsman professional one I have, its padded, rolls easy, and you can change out the casters if they fail
Sockets and such I say get a decent set like craftsman or similar, Mac and Snap on are ridiculously pricey unless you use them everyday, for the rig I have a decent set with everything I need, socket for CV flange nut, diff and tranny plugs, hex (think it's 10mm) for the front diff
Impact is def good, I'm a carpenter so I have good tools, Makita and Dewalt are best in cordless market IMO, Milwaukee also good, air tools go Ingersoll and Rand, Aircat, Chicago Pneumatic, get a set of impact specific sockets as well.
Torque wrenches I have an 3/8" drive 30-250 inch/lb, a 3/8" drive 10-150 ft/lb, and a 1/2" drive 30-250 ft/lb, all made by CDI, all steel clicker type, very reliable. You'll need the beef for doing heavy stuff like if you decide to do your own timing belt to get the main pulley nut bolt cranked back on to spec, and need the little guy for stuff like valve cover gaskets and other light duty tasks. The better the brand, the better the accuracy, the longer it lasts.
Once you start getting into the bigger shop tools, I like my Harbor Freight 20 ton press, love my Miller welder, have an oxy/ace setup, and the bigger the shop compressor you can get the better, especially if you plan to do air ram setups for presses, benders, and press brakes, and a good brand is important.
I fully believe the mantra you buy the best you can afford and spare yourself the agony of having it fail when you need it most. Each tool has paid for itself by this point, hell, the press was $170 on sale, and considering a shop will charge you to do the press work, and you have to take time work to get it there and down time while they do the work, it paid for itself the first time I pressed my axle bearing off. If you sign up with Harbor Freight they send you coupons all the time, and Northern tool has awesome selection to just drool over and add to your wish list.
Have fun, and welcome to the empty wallet club
