I'm New, Raid Questions

[Folly]

I've never played EverQuest. I'm the type of player that likes to be able to do everything. But I can't always have so much time to play. I'm fine doing slow leveling and grinding.

But raids require you to be at the computer for quite a while.
I'd like objective answers, how long does one need to be at the computer for a raid in an average guild.

And from reading some of the raiding post, there is all sorts of rules and rotations between guilds. Is that correct, do guilds have an agreed schedule for each other so they don't conflict? Or is there a lot of raiding conflict?

If I played 3 hours a day in the evenings, would I be suitable for a raiding guild?

Raiding is just something that scares me, I want to participate in it. I've never raided in any game.
