Is there a specific reason you want K02's? Those are a pretty ancient design by now and not very amazing at anything except riding rough. You would likely be much happier off with some Nittos, Falkens, or Coopers.
The wheel choice isn't bad, they work well on these trucks. Something in the 0 to -10 offset range will look great and be fairly easy to fit. Don't go with anything with a positive offset to avoid rubbing on internal components. I'm not big on the faux beadlock though and think the OEM TRD style looks a lot cleaner. There's a few different options but
these are nice if you're open to going with 17". I think there are some 16's available as well but I can't remember who makes them. The new Tacoma trail edition wheels look pretty cool too.
The cheapest and most cost-effective suspension lift on these will be Bilstein 5100 shocks. They can be had for about $400 if you do the install yourself (not hard but need extra beefy spring compressors). I don't like that they have to be disassembled in order to adjust height, though. The cheapest proper coilover setup I'd recommend would be the Eibach Pro Stage 2. They are sprung and valved much nicer than their Stage 1 kit for not much more. You also might gain a little bit of height swapping in a set of Off-Road take-off's. Can usually find them fully assembled with <2k miles for ~$300. They ride fantastic.
Depending on how much you want to lift and your wheel offset you may also need to look into changing out the upper control arms to some that support higher caster so you don't rub all over the place. The JBA's are a pretty hard value to beat and offer lifetime warranty, rebuild kits and everything is greaseable.
There is so much to look into regarding lifting these things and options available for just about anything you'd want to do, just will set you back some $ for anything medium to high end. My setup is fantastic but it definitely cannot be had for $3k lol.
