I like your attitude a lot because I'm basically on the same pathway. My plan has always been to avoid buyer remorse when it comes to tools, but also to temper my enthusiasm with regular doses of reality.
What has been effective for me may or may not be the right way for you, but I'll share it anyhow.
What I've done is to set specific task goals, and tool up as needed on a job by job basis. The key has always been to start with the goal, and working backwards from there to a well considered plan. The cruiser is not my daily driver so I can spend some time to do a bit of homework, explore my options, think about how my short term project fits into the longer arc of my overall plan, accumulate the materials and tools that I need, and then do as high quality a job of it as I can muster.
Since my motivation, perhaps similar to yours, has always been to make my garage into a learning lab, I've tried to make tool choices with an eye toward accommodating future potential. That's paid off for me quite a few times, but it's an expensive way to live and it's not for everyone.
Is that a recommendation for you? I can't say. You wrote, "Any thoughts?" so there's mine.
One of the problems is that a lot of different people have a lot of different ideas about their goals for Landcruiser projects. Some people do beautiful showroom quality restorations. Other people do "resto-mods" with extremely clean restoration AND performance upgrades. Still others build their cruisers for hard use or even extreme duty, where eventually the thing is so modified that there's not much of the original left.
Depending on what you're starting with and where you want to take this, you're going to have to prioritize the work and tool up accordingly.
