IIRC that was asked before and it was said to be not possible but i think there should be a way to disable it...
the problem i anticipate with the screen disappearing is everytime you open an app, the screen needs to load and close if you closed the last app leading to higher processor usage and battery drain, both of which are already problems...
I am pretty sure those texts are in the locale files.
There was a similar request for changing the
"I will call you later" text for the reject call message. http://talk.maemo.org/showthread.php?t=80587
you have to find the appropriate locale file
in /usr/share/l10n/meegotouch directory.
Copy the file to your desktop and use qt linguist to
open and change the text.
(But I don't know in which, if at all, file you'll find
the text).

By the way, some pointers:
1. Restart/reboot after overwriting the file.
2. Rename the file accordingly. For example:
- you have set your language to English (United States) in "Settings->Time and language", then you need to rename the file to "home_en_US.qm".
- you have set your language to English (as in English, not English United States), then the filename is simply "home_en.qm".
