Again, I haven't done this, so I cannot vouch for it. The article is also several years old.
Possibly. Although the last time I went through T3, somebody checked I'd got the SmartGate sticker on my passport before I went to the gates. Not sure if this is normal - and it didn't happen my last time at T1.
