using tos to handle priority works fine... when your router is configured to use tos! You just marked the packets, but then you've got to set rules on the switches/routers etc to use the tos fields. The machines on which to enable the use of tos will depend on your network architecture...
Setting the ToS bit only affects the immediate router. The upstream routers, such as the ones at your ISP, probably ignore it. A better plan would be to use an HTB qdisc, or a script like cbq.init to give a service such as SSH priority.
If that script doesn't help, I can give you an HTB setup that should help. Let me know if you need it.
CBQ allows for a more fine-grained access control mechanism than HTB, but most people wouldn't use that. It almost certainly won't give you much benefit. You should stick with HTB if you're going to write your own traffic shaping scripts, as it is worlds less complex.
