A mission ship needs to have 2 things. 1 - tank - the ability to keep your ship from exploding by absorbing damage and repairing your hull or recharging your shield. 2 - gank - the ability to keep your ship from exploding by preventing damage being done to your ship (ie - kill them before they can get within effective range of thier guns) You are flying a Vexor, the classic fit for this ship is armor tanked. A medium armor repairer and some armor hardeners, a cap recharger or 2 in the mid slots. This is how to fit a tank to a vexor. The Vexors other strength is its drones. I would get drone operatation to V ASAP and then combat drone operation to IV ASAP. Your aim with this ship is to maximise the damage that your drones do. You might not even fit guns until your drones are decent and your tank is effective. Once you find the right balance of tank/gank, the only other thing you need to do is read the mission reports http://eve-survival.org/wikka.php?wakka=MissionReports before you decide to accept a mission (dont accept a mission you are not sure you can do, otherwise you will have to quit it and lose standings) and once in the mission, manage aggro by being careful not to hit the wrong trigger ship so that you DONT pull too many bad guys at once. Where are you in space... what is your home system, I'd be happy to help by kiting you through a couple of missions.
