Bell device, new to rom cooking, need advice on new rom

[Kurt]

I have a Canadian Bell Mobility 6700. I'm growing very tired of the issues with notifications. I am having to restore from a backup about once a week in order to fix notification issues (usually getting a notification without the dialog so I can't dismiss it). I've resisted home-cooked ROMs for a long time, but now I just need it to work.

Now I don't know where to start. I've tried some searches, but my problem is that nothing seems really geared to someone coming at this issue new. I see what are new (to me) rom kitchens with patches for this and that. I don't want any extra software besides what the device came with (I prefer to install my software myself rather than have it rolled into an AKU ROM), and I want to make sure it stays compatible with Bell. I also want to make sure I keep my custom boot screen that I created. I use a Bluetooth headset and have never had any problems with Bluetooth on this device, so I don't want to invent new problems there if possible.

Any advice that people can give would be very appreciated.
