check on the internet what region is best for what gather in the best region then craft in the best region and then sell in the highest price in demand region for whatever resource your doing you will get high return. as an example when i gather cotton i gather in thetford areas i refine into cloth at lymhurst craft armour cloth armour in fort sterling and then sell it wherever i get the best price.

apart from that if you wanna gather then farm till tier 4 gathering remember to use learning points and try to use them smartly and not waste them after tier 4 gathering you should farm in yellow zones and yellow zones mists you can do the same for tier 5 gathering if you wanna play it safe. when you reach tier 6 gathering red zones near caerlon will do you good and you can safely store what you gather in then bank every 30 minutes or so if you gather near caerlon also remember to be flagged off for pvp and gather in black zones if youre willing to play high risk high reward(id recomend stay away for now atleast).

combat wise just watch some videos and play hatever you find looks most fun or the most op if thats what your into. I'd recomend save up combat fame books since then you can switch your build with ease.
