Here's my top 10.
1. Don't let bullshit family politics get in the way - this is your do and anyone who puts pressure can go fuck themselves.
2. Delegate specific, time-consuming, non-fuck-up-able jobs to your fiance making it clear when you need it done by. Anything that requires a value judgement or artistic interpretation should be done by you, similarly if there's one thing that he wants (even if you REALLY don't), do it - if he's making a stand on something it matters a lot.
3. Do it all in advance, leave nothing to the week before that you could have done earlier, because shit will happen and you'll have to deal with it (or not and you can try to just enjoy the lead up).
4. On the day, stop and look around periodically at people and the venue, it'll be over before you know it.
5. No DJ - I got my best man to do it (covered). No Photographer (unless you have a pro in the family - forgive the pun) just get people to take as many pictures as possible and delegate to someone you know has a good eye/ expensive camera to take the "official" ones - and if possible get someone to "bulldog" people around for photos - write out a specific list of pictures you want and give it to them to boss people around - this is the fastest most efficient way of doing it - it's still like herding cats but the pix get DONE. (photos that often get missed: bride with each parent individually and then together, bride with best men, just the girls, groom with all the girls, best men and bridesmaids, etc) make sure that you get the photos from everyone (disposable cameras on the table are essential these days) after the wedding - take a pen-drive to as many as you can and get the rest to send them to you on CD/DVD as soon as possible (people forget and move on)- do not rely on photobucket / facebook as the reproductive quality is awful. Then use blurb or whatever to put together your album (do this quickly after the wedding / honeymoon as otherwise it'll get put off and never finished).
6. Get people to video as much as possible, even if it's on camera phones or whatever - there's lots going to be going on and you'll be missing most of it so it's a great way to be everywhere at once (and to catch people drunk at weddings) and it's a doddle to put it all together these days.
7. Give people jobs, yes they are guests but they will also do pretty much whatever you want - I find that male partners of your female friends are the best for this - they often feel excluded ("i don't know anyone...") and as the bride, giving them a techy job with a bit of authority makes them feel like they have a reason to be there and mingle. Female friends who aren't bridesmaids can be given supervisory jobs - watch out for uncle knob-head, don't let so-and-so get blind drunk before the meal, talk to grandma, etc. But don't micromanage - prep your bridesmaids / bestmen to roll out these instructions.
8. Save money on everything you can (we had nice but cheap candles and centrepieces - again big shout to Michaels - if only they had them in the UK), work out what is essential and what is not, then look at what the non-essentials will cost. I printed out the orders of service / invites / seating plan myself and we saved a bomb.
9. On the day don't obsess, it's too late to do anything and you'll just come off as bridezilla, roll with the punches and use your bridesmaids / best men as servants - if something needs doing - delgate to them, they are there to help.
10. Don't do it. But if you really have to, nail it the first time because you'll never want to go through it all again.
