Bottles:
If you use, rinse with warm/hot water, then dry upside down then yes, you can store them in a dust-free/dirt-free environment and sanitize the day of bottling.
Equipment:
For buckets and carboys, I pour about a 1/2 gallon of diluted star san (no rinse sanitizer) into the vessel, shake it around, put foil over the opening or use the lid for the bucket, and let that sit. Another quick slosh of the sanitizer before racking is done when I am ready.
Spoons, siphons, etc, are all sanitized using a 30" long wallpaper tray. It was the best $14 I could have spent next to the vinator. I toss those in while the wort is cooling. I use a spray bottle of star san to just do a quick spray of things as I am working.
For me, the best thing to do and something I didn't know the first time around, was to make a 5 gallon batch of star san and just leave it for the duration of my brew. That is brew day through bottle day. I keep it about a month, maybe 5 weeks, and dump it. I could measure the pH to determine if the sanitizer is still okay, but I don't.
