Not at all.

Probably.

Do you really think that someone could do something from the outside to cause
physical damage?

SPI or not, if someone decides they don't like you, they can cause huge
quantities of data to flow your way and no amount of filtering or
firewalling at your end of the bit of string will make any difference.
You can stop it going through the router (NAT alone ought to do that),
but not stop it getting to the router, and by the time it's reached your
router, it's too late to do anything about it other than throw it away -
it's already clocked up "wire time".

You want (a) a good ISP - none of your 9.99 a month rubbish, and (b) a
router/firewall that can do outbound QoS.

Which ISPs support outbound qos. I thought QoS at the moment was only
really handled in your LAN.

It is. But what you can do is limit the 'damage' caused by outgoing
traffic leaving your LAN to the world wide wait. E.g. uploading large
email, p2p traffic and so on. As incoming is usually much faster than
outgoing, it's less of an issue (most of the time)
