Heck, don't even respond to the email threat. Just report it to your local Internet crime department, toughen up your online presence and take the hit and laugh at the scum...
I had some DDoS issues last year and I use a small to medium boutique host in Singapore. He's a top notch guy who really knows his stuff and has his own space in a mainline datacentre in Singapore (my traffic is mostly from Asia). He worked together with me via MSN to mitigate the attack. He spent loads of time with me and as a result, won a customer for life.
Long and short, don't ever encourage these fraudsters with a response of any kind. Get a better host if they can't mitigate the attack with technical superiority. Use the experience to shore up your online assets.
