Heheh I keep dogging at you heels.. anyways, I am just learning the ropes myself. Combat seems pretty complicated at first, there are a bunch of things to remember, all those maneuvres and actions, SR and and so on. What helped me was to use the combat cheat sheet which includes all the maneuvres (the link is someplace on this forum and Mongoose's website), and I didin't worry about fatigue to begin with.
Also, as we play Clockwork and Chivalry, the adventures have these handy summaries of the NPC with their stats and skills in neat tables with room for notes and wounds, and prerolled SRs etc. By doing some of the work in advance you save some hassle during the play. Then it's just a matter of asking the players to roll their SR, put them all in the correct order (actually markng the order and SR on paper) and go from there. Next I am starting keep book on fatigue, as this is pretty important.
And one important tip: try to keep tabs on hit die rolls from the beginning. Tell the players to leave the dice alone on the table after rolling them to hit etc. because that result is often compared to another roll byt the opponent, ie. opposed die rolls.
