I'm still working out part 2 of day one myself. I should have it up in a bit now that I've identified a better strategy. But I may as well share my part 1 now:
The key thing that made my first attempt fail was overlap between words. eightwo.
This is a problem because it wants the first and last valid word. My first attempt was destructively translating the text to the format that the part 1 code would handle. eightwo -> 8wo.
So the working solution I ended up with translates each line into a list of all valid numbers in the line and their position. We then sort by position, take the first and last, and the rest is math.

i like this idea. i am very tired, and very busy. but i will try!
This is my part 2:
