When I do a traceroute6 it takes 11 hops to get across the tunnel. Is this normal or am I having a routing issue?
You forgot to show the trace...please show, and please don't obfuscate it, thanks
I didn't thing that you would need the trace route to say if 11 hops is normal.
But here you go:
traceroute6 ipv6.l.google.com
traceroute6 to ipv6.l.google.com (2001:4860:8004::6a) from 2001:470:d:d69::1:118, 64 hops max, 12 byte packets

What's the TTL on your tunnel interface? This one got me in the past.
I did not have one explicitly set, I added "ttl 64" to the interface definition and it works!
Is there a value for ttl that you would recommend for the tunnel?
The commands given to me by the HE configuration script specify it at 255. But I have no idea whether that is good or bad.

Without a specific TTL, I bet it was set to "inherit" so it was counting how many IPv4 hops the packets was tunnelled through.
