I'm going to try and pass you my strategy experience on what to do to win a "comfortable" victory in a few words.
First of all in Civ 4 there can be NO comfortable victory.However having in mind certain things can make your opponents tremble you.
In ancient times: Try to expand and get your economy started.Create a couple of workers and automate them to do the job.Keep your defence high to deflect barbarians.Theocracy civic would be a nice idea to stop the spread of other religions in your grounds.Also keeping your borders closed until you HAVE TO open them or your safe to do so will warranty a peacefull and "easy" ancient era.Focus on culture and science to take an early advantage upon them.
middle ages: Keep your culture and economy your high priorities.Keep your borders closed and drive hard bargains with your opponents.Maintain peace at most cost.This is the most critical phase of the game.If you fail this era the others will take a good lead upon you.By the end of the era apply State property and bureocracy civics to keep low cost and high production.Pacifism would be a good idea if you don't have huge armies or it will raise costs to the sky.
Modern times:Win the war before you go to war.Hurry up and control oil and uranium resources all over the world.Fight if you have to.Start building a giant war machine, and run for the nukes.it's about time to open your borders.
Enemy can no longer expand through them and spreading his religion would cost you nothing with the free religion civic.After you've built 5-10 nukes, ask the opponents through UN to vote for non Nuclear proliferation.If they say no, let the computer be the president of UN.When he will propose,they will all vote yes
Drive your armies to war and devastate your enemies or keep it going for the cultural victory
Either way you win
