Samsung Fascinate :: Eris And Palm Pre Plus - - Alarm Clock - GPS

I've been reading a lot about the droid x and the fascinate.

I like my palm pre because of the webos, but i really really hate the keyboard and some other minor annoyances.

I had an eris before and it was ok. i still have it and use it mostly as a kindle for reading in bed at night.

Here are my questions:

1 - on the Eris, my main complaint is that when reading on the Kindle app in the dark, the soft keys light up and are really bright. is there some sort of patch or something that i can use so that that doesn't happen on the fascinate?

2 - alarm clock - the palm pre plus does not have a separate volume for the ringer and the alarm. if i set the alarm, i have to be prepared for any other notifications to come thru as well. on the fascinate, is there the ability to silence everything BUT the alarm clock?

3 - GPS - i use google maps a lot and go to big cities on the East Coast frequently. some of the droid x/fascinate threads say the fascinate gps is laggy/inaccurate. has this been the experience of users in ny/dc/baltimore/philly? i know that in my mostly podunk town, gps can be off by quite a bit, but much more accurate in larger cities. not sure of the technicalities behind GPS so maybe it's just my imagination.
