Side question: Are there any pics of the Phase II Starfleet officer uniforms?
The regular Starfleet uniforms from TOS were going to be used with a little modification. As Therin points out, several were auctioned off at Christie's and currently by It's A Wrap on ebay. James Cawley, of NV/PII, has purchased several of them for use in his ongoing fan production. They will be seen in the upcoming episode, "Blood and Fire."
Here he is in the command shirt sleeve:

Here is the working jumper:

The short-sleeved dress can be seen in the engineering test shots on the TMP dvd and in the pictures in the PII book.
Thesis also played with putting various seems and darts on the standard tunic to make it more interesting (some were seen at Christie's auction), but he dropped it and kept the basic line of the original. He used a different, iirc, nylon material than they 3rd season TOS uniforms, and made the collar a bit higher on the neck. He also changed the pants to have a vent in the cuff.
The TOS uniforms that are part of the Star Trek Tour are actually uniforms created for
Phase II. (

You can tell be the material, the vent in the pant cuff and the higher collar which is made out of a ribbed material and not the spring weave of the original series. Also, the uniform was incomplete so you can see they used TMP braiding to finish the rank off.
James Cawley favors the higher collar in his production and has also used the P-II style pants as well with the primary cast.
