Four skills. A weapon skill, a shield skill(unless you're a marksman), armor skill, AND wrestling.
Wrestling from what I understand makes you harder to hit, also makes you tougher or more agile I believe.
I have a hammerdwarf who balanced his points between those four skills and he just mows through everything. He has been scrapped up a few times but I've always been able to kill my adversaries so I can scurry off and heal afterward. Most if not all injuries will heal quite quickly in adventurer mode if you don't die right away.
When in combat, be sure to always stand up whenever you're knocked down. Being on the ground reduces your speed so that enemies get 3 to 4 attacks to your 1. Also, try to maneuver so that the enemy closes the last bit of distance and therefore you're the one that gets to initiate the first attack.
Note that the weapon, shield, armor, wrestling combination doesn't make you a juggernaut right away, you still have to be careful. For starting opponents, I recommend harpies, harmless-sounding wildlife (moles, etc), and also the things that you encounter in abandoned forts and caves. Goblins, troglodytes, those kinds of things. You have a fairly good chance of being able to take on opponents 1 by 1 in those situations, but if you find yourself against multiple targets try to disable or stun them one at a time then switch to a different target in order to limit the number of enemies hitting you at once.
Oh a few more things. If you do go marksman, ammo is hard to come by so be prepared to scavenge a new weapon and a shield anyway. Switching weapons is a bit tricky, just drop the things from both hands then pick up the weapon you want to attack with first so it goes to your dominant hand. Dropping takes no time, but you'll pass a turn when you pick something up.
Also, look around NPC dwarf forts, towns, fortress retreats etc for basic weapon NPCS. By that I mean, axedwarves, swordsdwarves, elven swordsmen, whatever. Talk to them and see if they want to join, if you want help. They help quite a bit, the only problem is they have a tendency to get the last hit in on monsters and therefore take your glory. By that I mean if you kill Ixthubiko the Cyclops your character gets a mention in the recordbooks, but if Jojunjim the Axedwarf gets the killing blow, then Jojunjim is mentioned in the legend instead of you!
