How many nights will the Goal Zero Yeti 500 run an electric blanket?

Not a full night: about 5.5 hours, short of 8 hours. An electric blanket averages about 75 W (150 W running, on about 50% of the time), and the 499 Wh battery gives about 424 Wh after inverter losses.

Can I run other things at the same time?

Yes, up to about 350 W more of the 500 W output. Each thing you add shares the same battery, so the 5.5 hours for an electric blanket gets shorter.
