Syncing your iPhone in iTunes isn’t the way.  This is how to do it on a PC.
This method imports your pics and vids into your My Pictures folder.

Here are a couple of the highlights for Vimeo encoding :
Use 2000 kbps for standard definition or
5000 kbps for high definition video.
For audio: data rate of 320 kbps
sample rate of 44.1 kHz

If you decide to use the Media Browser in Premiere:
The layout in CS6 has changed from CS5.5
Detach the Media Browser Tab by holding down Command and dragging on the gripper
This floats the panel
Browse and view footage
If you like the footage, drag it to the project panel (which should now be visible.)

Storyboard
This is a very fast way to get your “video wedding story” down on one layer
Select all your video footage in the project panel and copy
Make a new bin (folder) and name it Storyboard
Paste into the Storyboard folder
Change the view to Icon.
Select footage and play in the small window to view.
If you don’t see a little video preview, access the palette options to select this preview option or …
Double click and watch in the source monitor
Arrange videos in order by dragging. This is your visual “storyboard.”
Select All
Hit the small button at the bottom called Automate to Sequence, then hit OK to accept defaults
Now you have all your approved videos in order on one layer.

Layers
Set in you mind a number of layers and limit footage to that number.
I would like to see only 3 layers at the most.
Delete layers that have visibility turned off most of the time.
Use the power of non-destructive editing which is … DELETE!
You can always get it back again.
Do a lot of Save As Name001, Save As Name002, at critical points,

Multiple sequences, Nested sequences
Create story events with multiple sequences with names like “Preparation,” “Down the Aisle”, “Celebration,” etc.
Later you will make a new Final sequence and drag all the event sequences into that  main sequence, in a row.
Make new sequences using the new item icon at the bottom of the project panel.
Name appropriately. Add clips in order in each sequence.
At the end, drag all your sequences in a row into a sequences named Main Sequence.
Try cross dissolving one sequence to the next to indicate progress in the wedding story.

Audio
Use the Effect Controls window to easily create keyframes
Download Audition
Control click footage with audio to edit. Try and find a filter that works for your particular audio problem.
Start with Effects/Amplitude/Normalize and Effects/Noise Reduction. These are your best bets.

Audio and DSLR video, the big picture
Look into getting a Zoom H4N to help  capture better audio
You can also get a boom/shotgun microphone to target the main ceremony and diminish background chatter
The software called Pluralize aligns audio and video, but the Zoom can record direct to your video’s audio track using your camera’s audio input..
The Zoom inputs into the camera and accepts multiple microphones and has 2 onboard mics, better than the top or the line Canon EOS DSLR.
It does create a lot more to manage during a shoot — an assistant with headphones might be required.

Overlay from source monitor
Double click source footage you want to use
In the source monitor, set your in and out points using { and }
Hit either the Insert or Overwrite button (it works fine now.)
The trimmed clip lands on teh timeline and the current time indicator jumps to the end of the footage
Do the same for the next footage … this is a great way to start a project on one video layer.

Color
To warm color use the fast color corrector as you have been
Use the RGB Color Corrector effect and drag the Gamma to increase dynamic range
The 3 Way Color Corrector has color wheels — it is great because it gets the effect of controlling shadows separately from midtones/hilites so you can get a real look going.
Luma Curve is good to handle luminosity on a curve — start with make\ing 2 points, one for highlights and one for shadows and make an “S” curve shape.
Gamma Correction is great for fixing washed out shots.

Rendering
Use H.264, I would experiment with a slower bitrate range if the files turn out to be too large.
Set e your video target birate settings to 4.6 and 5.4 — if they are currently too high.
Bring the audio down to 44100kHz since Vimeo will not handle anything beyond that setting.
Bitrate settings for audio — you can bring this up to 320, the maximum setting for Adobe Media Encoder as well as Vimeo. Vimeo video and audio settings
