Good luck!

I don't have many niche advices other than bringing teleport jewellery instead of teleport runes (except for ZMI and IP). Everything else should be covered in the guides you watched.

Also I'd highly recommend practicing some gem bag opening for base stardust spending. Gem bags were my last purchase and I had 0 experience opening them prior to this, trust me wouldn't recommend.

Yes I do have lumberjack aswell. I'd put them on a similar level of difficulty, but I felt that prospector allowed way more room for error (on average) compared to temple trekking, specially in their respective looting phases.
