For a sword fighter, you'll want to focus having gear with Strength.
As a new player, put your first 10 stats into Vitality so late on, you won't have to worry about dying as much.
The main stat in the weapon you want to be looking for is Enhanced Effect. The more EE on the weapon, the more damage you'll be doing.
However, keep in mind, the higher level you are, the less effect a lower level item will have. (i.e A level 20 sword with 60 ee would be about 24 ee by the time you reach level 30)

The more strength, the more crit's your sword will be doing when looking at the ratio for swords (75/25)
http://ladderslasher.d2jsp.org/index.php?g=3This means that swords are most effective when your stats are equivalent to 75str/25dex. However, many players simply invest all their points into STR and I suggest to do the same.
