Well. If you have a decent amount of money, the Goblin Mace would be a great unique for you if you have the means to upgrade it. Otherwise, I highly recommend getting a Mace with Physical Accuracy to help your hit percentage. Yes, it might seem like low levels don't need to enchant, but I think a few percentage points can really help.
As for armors, you probably should just update to the next set whenever you can (does not mean you always have to buy it). Most enemies that you grind/quest on will most likely drop equipment that you can use. Alternatively, you can check Pie's Quest Guide (under Quest Guides in the Guide Section of the Forum) to see which quests give out pieces of armor as a reward.
Once you get to a high enough level, HP and Stamina is recommended to help you survive against large mobs, but again, not necessary.
An alternative would be to start collecting Hyunmu Armors from the Instance.
