You can buy the highest quality enchants and apply them yourself. There is no crafting requirement to apply a glyph. For traits, you can transmute a piece of gear to any trait you want but you must have researched that trait on that item. So if you want to transmute a pair of gloves from training to divines, you will need to have researched divines on gloves. Researching can be done with no skill points invested in crafting, but it will go faster if you invest some points. Researching also starts out quick and gets slower the more you research, so research the popular traits first. You can research your first few traits in hours. Later traits can take weeks, so leave the unpopular traits until last.

Generally, there are plenty enough skill points in game to max out all the combat skills you want and still max out all the crafting. Most people becomes master crafters on their main character. But if you really don't want to learn crafting, you can mostly get away without it, even at endgame.
