  so you're asking two questions at once it seems?
  yeah, std firewall and you wanna queue your upload, shape on ISP-facing
  interface.  if you want to shape traffic on both directions, you can
  approach that by shaping your upload on ISP-facing iface and shaping
  download on LAN-facing iface.
  as far as shaping both on a bridge:

  i really don't know if the scenario is any different for a bridge, but
  i do queueing on both packets from my LAN to the world ( upload )
  and also on the LAN-facing (internal) interface, queueing on packets
  which are either between the firewall and a LAN host as one set of
  queues ( for 100Mb ), and for packets which are from the world and
  going back to a LAN host ( for my ADSL download ). 
  for things like ftp proxy, that would normally match firewall<->LAN
  rules, so i make a special rule for 'from firewall to lanhost user proxy'
  which queues it to the "external/download" queue on the internal iface.
