For the first Thieves mission, just go straight up there and straight back out, doesn't matter if they see you, if you're quick enough you won't get done.
And for the vampire thing, look to the Brotherhood.
I too think it is very silly to apply such out-dated terms as Fascist and Nazi to modern-day world powers.
Nazi stood for National Socialist anyway, it wasn't some doctrine of belief. They were just led by a bunch of very strange people.
You should do what I did, and refer to Jordan for expert advice on the KVM solution. That or search the tech forum for the topic I posted a month or so ago.
All the people who've said that paedophiles should be locked up because they might cause harm advocate thought policing. We all know where that's gonna land us.. in Lack-of-Liberties City drinking cups of Victory tea.
Yeah you don't get booted out of the Thieves' just for joining another faction. It's quite safe.
And Orming, you want to get out and fight some beasties in the wilderness to level up. The two graverobbers are actually pretty tough, so get some levelling done first.
Doesn't always work quite like that though. Sometimes it's more like; it did happen, but I never remembered it. For instance, if one were to break one of one's bones whilst intoxicated.
I don't think it'd be easy to get a guitar which can do both Dylan and Libertines styles. I think Barat plays some sort of Gibson/Epiphone thing, which would not be easy to emulate on a semi acoustic. Likewise, folk would sound strange on a guitar built for electric riffs and that.
If I were you, I'd go get two guitars.
