Haha, yeah. It does tend to cascade a little. I had to go re-evaluate all the stuff for the nuclear reactors and anything using advanced machine blocks but I still may have missed stuff though, as I only notice when I get round to building something and think "Hey... that doesn't look right".
Further, all the itemIDs are different between Tekkit/Technic it seems (understandable), so I had to redo everything from scratch, but your list was a great starting point, so many thanks for taking the time to put it together. I'll link my own one later for anyone that wants to take a look at my version for Technic. I've probably translated about 50% of your list, but I've not got round to porting over the stuff you did for potions, or any of the RP stuff yet, it's mainly IC and BC as that's what I tend to rely on when I play Technic.
Not going to get to involved in the EE vs. Creative Mode debate, but I will say, is that Minecraft is probably the epitome of "play it your way" games, and I find that being able to condense things strikes a nice balance between the freedom of creative mode, and the fun and satisfaction of making everything from scratch.
