To bring your spotlight back, run the following commands in the terminal:

sudo chmod 755 /System/Library/CoreServices/Search.bundle/Contents/MacOS/Search

killall SystemUIServer

The problem with removing sleepimage and making sure it can't be written to is I'm pretty sure that if you run out of batteries, your mac will no longer hibernate (save RAM to disk) but will simply ungracefully turn off, and you will lose current state of all apps without warning.
