She MAY be able to export OMF: it depends on if her PT is version 9 or later (or if she paid for the privilege with the earlier versions). Otherwise, she will have to export the tracks.On the other hand, if you are only tracking and not mixing, she could just give you stems or a full mix sans vocals.Alas there is no "import DAW X session" tool.

Actually there is Pro Convert by SSL and AATranslator, both of which convert between DAWs, but they are both paid software and have limited ProTools support (the former only goes up to 7).
Also the problem with ProTools is there are not necessarily equivalents of all RTAS/AAX plugs, so you'll lose plugin settings at least. When I tried to use a ProTools made OMF I ended up having to use a trial version of Reaper to load it, and then export the tracks as wavs to load in Sonar. It's really not worth the hassle, IMHO.

Starting to worry now that my only option is to see if she has a stereo mix so I can hear what it should sound like, then experiment bringing all the wavs in and put them all where I think they go. Hours of fun guaranteed.

I work with PT and Sonar.
 
There is no way of doing this without trial and error. 
 
OMF is the way to go but that can kick up errors. (trial and error)
 
100% the best way is to get stems from PT to import into Sonar.

Stems is definitely the way to. I've received stems before. That's fine. It's the not having any access to PT to create them that's the stumbling block here.

Here's what I've done in the past...request all of the audio tracks be sent as .wav files, with no effects. Even if you have the plugin data, they won't work because more than likely they were PT plugs that were used. Just make sure the .wav files are all exported from her PT session from the same start time, otherwise they won't line up when you import them into Sonar.

This is the easiest way. As stated as long as they all start at the same place. If they do its simple!

If you have the .wav files you can just select them and drag them in to a blank Sonar Track View field. That worked for me, and they did NOT all start in the same place... I assume they are time coded somehow.
 
You can try and see what happens (it worked in X2 and still in X3 for me with Pro Tools wavs).

If you ever NEED pro Tools, just buy one of those cheap Avid interfaces, as they included a free version of PT Express.
 However, it is very limited. And if you are in a crunch, just download the 30 day trial (you just need an iLok).

How do I drag the files in? Surely they will just be inserted at the Now Time.

I could help you out, but unfortunately I can't make the Thursday deadline. I'm too booked over the next couple of days. If you could get the session to me before the weekend, I could have something that you can import into SONAR by Monday.

Either use the import function or drag and drop from the media browser or windows explorer. If the files are broadcast wave files, where the files are placed in the track depends on the Preferences > File > Audio Data "Always Import Broadcast Waves At Their Timestamp" setting. If the files are not broadcast waves they will line up at the Now Time.
