If you have an EU nationality the paperwork (getting a SS number, a tax card, registered residence) will take maybe 3 hours of work once you have a signed contract. I've been through it and it's surprisingly agile. I don't know about non-EU nationals, though I know people from the US and Canada who managed to get an EU nationality because of their grandparents and simply used that to avoid worrying about visas and all. That said, the companies will be very helpful if you need assistance with paperwork so you should be fine when it comes to it, though I doubt you'll need the help. About the language, English will be fine for nearly any tech company. That said, I'd also check out Berlin and Copenhagen; big startup scenes there. Never worked in The Netherlands so I can't speak for Amsterdam, sorry.
