i always filled one, and just set a cap on top to allow any air to settle out. once i had them all filled, i go back and start capping them, starting with the first one i filled. maybe i was crazy, but it made me feel good :~)
Strange maybe, but it works for me. To start, I put six in a bucket of iodophor solution.
Let them sit for 2 minutes.
Take them out of the solution and drain and shake well.
Sit them on some wax paper, or cling wrap, or whatever.
Drop six more in the iodophor solution.
Fill the first six and cap.
Put them in case.
Take the next 6 out of solution and repeat all over again.
This way, they all stay in the sanitizing solution for about 2 minutes. Keeps me from getting in a hurry and taking them out early.
I leave all of my bottles in a box. set the box on the floor, fill 'em all up. go to the next box, fill 'em all up. for 48 bottles, it takes about 10 minutes to fill them all. then I recruit some help(usually my 11 year old daughter) and she puts a bottle on the table one at a time and holds it while I cap it. It usually takes about 10 minutes from start to finish to cap the bottles. So the whole process takes roughly 20 minutes from bottling bucket to capped bottles. Never worried about contamination and never had any.

Edit: This process is after I sanitize the bottles....like right after within minutes. I would not sanitize the bottles the night before and then bottle the next day.
I fill every damn one of my bottles before I cap any of them. I *DO* sit the caps on the tops after filling them so that nothing flies in there. Often, the caps are jigglin' like a stripper from the escaping CO2 by the time I come around on the second pass to seal all the caps.
My process is exactly like that of LoopMD except that my daughters are older and they don't help. And I use 12 ounce bottles, so I need more like 56 or so. I put my caps in a bowl of no-rinse sanitizing solution and only take them out when I am capping. Never any contamination problems to date.
I am pretty obsessive in my bottle sanitizing process.
I do them in 12 bottle batches to break up the monotony. I rinse them in warm boiled water, and then they all get sprayed with sanitizer prior to bottling. Now that I am using a lot of flippers, I just spray the flipper top down when I set the bottles up to fill, and still do 12 at a time.
