Firstly, a word of caution about jewellery. Always try to ensure you have at least some control without it. Otherwise if you die and forget to put on a jewel after resurrection, you may end up with a very p'd off pet. Often you want that pet to look after your newly-res'd butt, so it's a good idea to ensure he will obey
Sod's law of pet control = when it most counts, the RNG will fail a pet command... So use it with care
Taming is a git to gain past 100, so you won't likely pass 110 for a while anyway. Personally I see no reason to do more than train real skill to 110 and use jewels for the rest when you go out taming. That's the only time you really get benefit from 120 taming
As for vet and lore, well they raise relatively easily to 120, so I think they're worth training as high as you can afford. They're skills you'll use all the time in a hunt situation, and it's lovely to resurrect first time, every time. You don't have to have them at 120, but I do miss them on my younger cramped templates
