Noob needing some direction...

[LocalHero]

This AM I had some time so I flashed back to the DC22 rom to refresh my mind on what the original base is. Is it beneficial in any way to start from the offical DC22 update rom when flashing a custom rom?

Anyway my thought is that now I'll look for a very basic rom based on DC22 that I can then add features to. Is that likely to work well? If I add a bunch of disparate components am I just likely to come up with conflicts? I'm talking about custom dialer, alarm clock, theme, and the like.

Looking at the roms on Modaco it's hard for me to tell which ones are stable, bare bones roms that I can customize.
I'm assuming that I need a DC22 based rom but while at Modaco I now see reference to DC23....is there a new update?

Couple more questions; is there a way to disable the auto-lock feature on the phone? I'm talking about the whole device lock not the keypad lock that kicks in while in conversation. I'd rather just choose to lock it manually but I've searched for some time without finding a solution to this one (though I find others have been asking the same question)

Also, the phone keeps coming up with some kind of alert in the middle of the night. Last night about 3AM. I'm thinking it's telling me the batt is charged. I can't find a way to turn that off. Under "Sounds and Notifications" there is the "enable sounds for events (warnings, system events)" but I have no idea what warnings and events they're talking about. Do I get to choose which warnings and events I would want an alert for? I realize there's some options for this under the "notifications" tab but it seems like an incomplete list.

Thanks,
John
