Anyone used miles for Arsenal tickets as an away fan?

Looking at redeeming for a couple of tickets for one of the upcoming games but the relative I plan to bring with me is an away fan. eg

- Are the general admission tickets in a specific section with other Emirates / corporate ticket holders (and presumably therefore a bit more mixed in terms of support)
- Ok to wear away top?
- Are there any specific rules for the Suite tickets? Eg I assume a dress code so no sports shirts but ok to wear away scarf?

Am I overthinking this? Not been to a premier league before...
