Well before you gain any uber archer skills, your just a figher, and from my experience so far I recommend using more than your bow to take out mobs.
here are some tips for lvls 10-20
1) I like to power shot a mob, then let him run over to me and i trash him with a sword. The targets i can take out in one hit just take too long to level up past lvl 10, so the combo works faster to hit bigger mobs and gain more XP. Your MP will drain faster but, the power shot will knock out at least half of your enemies HP, then the sword will do the rest, buying you some time to rebuild the MP. I just hate shooting and running, then shooting and running. With some decent armor (wood, you can take a beating, while efficiently killing monsters).
2) On the note of using more then your bow in early levels, the SOS quest is a decent way to make some $ and get a good sword. I recomend holding off till around lvl 11 or 12 for SOS, by that time you have some skills set up and some money. I would then upgrade your small sword you've been using to dish out those combo, and buy a using SOS sword from someone finished with the quest (rent to own). On your way off to the dungeon go to the training room, and talk to the female trainer (Minia or something like that) and take your arrowhead quest. You might as well be killing to birds.
Once in the ruins, go to the first room on the left. It's easy, all passive, and they spawn in the same spot over and over again. Now camp on the ORC snippers, they will eventually give you the sword peices and arrowheads. It took me about 30mins to get the sword and 10 arrow heads. Go back to town, sell your second SOS, and cash in the arrow heads. Now you have a nice sword for your bow combos and a little extra money.
Then just save up and level up for a better bow, and if you haven't played yet, at least below lvl20 you can get all the skills with the SP given, and after 20 is when get specific, so use them all on your path to archer or whatever.
