i did many MB non-retina glass replacement but never a MBA LCD screen replacement before... is it worth getting a Air compressor for this job to remove dust and avoid any fingerprints on these backlight sheets?
use an anti static feather duster, if you get fingerprints on the lcd you can use low stick tape and roll it gently on the lcd, it will lift prints and glass, as for the backlight I wouldnt want to touch it with anything
