Heres what you should do, first pick what kind of account you want
Gmauler - This account is very effective at rushing, because at about 80 strength you can hit 30-30-30, combined with Ice Blitz/Barrage, very high amounts of damage can be taken in about a second.
Stats -
50 Attack
80+ Strength
80+ Range
82/94 Magic
Hp ?
Basically these things either just plain rush, by casting ice blitz/barrage, and then gmaul special, or range and then use the maul as a ko weapon, or they melee with a brine sabre/rune scimitar/leaf blade sword and then use the maul as a KO.
DDS/DClaws/DScimmy
Stats -
60 Attack
80+ Strength
82/94 Magic
Preferably 70+ Range
These accounts use dragon scimitars to lower the hit points, and then pull out either dragon claws or a dragon dagger to special and attempt to KO their foe.
Basically I would start off by doing some quests
Waterfall
Death Plateau
Fight Arena
Gnome Stronghold
Tree Gnome Village
Do Pre Reqs for DT
Desert Treasure
Get Mithril/Adamant Gloves
And then play a little with 50 att, and if you like it, keep it! If you don't like it, move up to 60 att, however remember that although you can always gain levels you can never lose them.
