Advice for a Hunter

[Sabra]

My level 14 hunter is being offered two abilities that I can't assess: Eagle Eye and Eyes of the Beast. She's husbanded her money carefully and has some very useful abilities at lv 18, so I'm trying not to spend on things that aren't really needed. Are these skills worth the silver and what are their benefits?

My pet has 70 training points and it seems that I'm the one who trains him, but I can't figure out how I do this. Does that skill comes at a higher level or is there somewhere that I have to take him? This might be clearer to me if I read through the entire skill base when I visit the Hunter Trainer. If that's the answer, just tell me and save your time. I try not to read too far ahead and spoil the surprises.

It seems that in order to get the full benefit of the hunter's art, I'll have to train a number of pets. Currently I have a sabretooth. Is it wise, when the time comes, to try different "classes" of pets: cat vs. vs owl vs. sea creature of some kind? Is that the way to get the greatest benefit from cross-training?

So far, the Hunter is the most interesting character I've played, but it seems like there will be a lot of skills (ranged ... melee ... pet) and one could be stretched thin. Any advice on managing the versatility?

Many thanks.
