Confused about my project settings - Can someone advise?

Question

I have some clips of my child when she was very little (i've supplied a sample at the bottom). I want to make a project with them in Premiere Elements 10.
I've tried using Premiere Elements' auto project settings advisor (i.e placed the 1st clip of the new project onto the timeline so it can advise if the project settings are correct or not) but no matter what intial project settings i use Premiere Elements doesnt suggest auto corrected settings. So, I've used 3 different media analisis programs to tell me what properties my video clips have and they all say different things:
1) Media info says: AVI (Mjpeg) 720x480 (3:2) 30 fps NTSC, interlaced.
2) MovieScanner says: AVI (Mjpeg) 720x480 (4:3), 480p (progressive).
3) MediaTab says: AVI (Mjpeg) 720x480 (3:2) 30fps, NTSC progressive.
So, i think i can safely say the clips are AVI (motion Jpeg), but are they interlaced or progressive (it's obviouisly important for me to get this right when choosing the project settings)? I have no idea what the pixel aspect ratio and all that would be as that's getting too advanced for me.
Can Mjpeg even be interlaced? Surely if it's lots of Jpegs put together to make a moving image then they must be progressive, or can the Jpegs themselves be interlaced?
Here is a very small sample clip if somebody wants to download & have a look for me:

Any tips of how someone would go about finding out these settings would be great too.
Many thanks.

Your wisdom here would be greatly appreciated (again).
I've decided to make my new movie project of my childs' 1st year in Premiere Elements 12 (not 10), and with the following settings:
The clips i have are of her 1st year and are from the same camcorder. Unfortunently (as previously described) i changed the settings on the camcorder half way through the year. So i have 2 sets of clips i want to use if possible.
The clips are in date order & comprise of the following 2 sets of properties (info from MediaInfo older version 0.7.47):
Set 01:
Format                           : JPEG
Codec ID                         : MJPG
Width                            : 640 pixels
Height                           : 480 pixels
Display aspect ratio             : 4:3
Frame rate                       : 30.000 fps
Color space                      : YUV
Chroma subsampling               : 4:2:2
Bit depth                        : 8 bits
Scan type                        : Progressive
Compression mode                 : Lossy
Bits/(Pixel*Frame)               : 1.161
Stream size                      : 144 MiB (98%)
Set 02 (you have a copy of 1 the clips from this set (2010-12-20 - emily in jersey.avi)):
Format                           : JPEG
Codec ID                         : MJPG
Width                            : 720 pixels
Height                           : 480 pixels
Display aspect ratio             : 3:2
Frame rate                       : 30.000 fps
Standard                         : NTSC
Color space                      : YUV
Chroma subsampling               : 4:2:2
Bit depth                        : 8 bits
Scan type                        : Progressive
Compression mode                 : Lossy
Bits/(Pixel*Frame)               : 1.158
Stream size                      : 93.5 MiB
Now, i have a stumbling block to solve and your advice would be hugely valued:
What project settings should i use (i ideally want to use both sets of clips in the same project, sorry, lol)?
I'm very tempted to use the project settings that Premiere Elements 12 suggests. It suggests a project setting for clips from set 1 (but has no idea about the settings for Set 2). There are more clips in Set 1 and so it makes sense to me (at the moment) to choose those.
The suggested settings from Premiere Elements 12 are:
Sony XD CAM EX 720p
timebase 30.00 fps
640 x 480
square (1.0)
no fields (progressive scan)
30fps timecode
The clip information that Premiere Elements 12 displays for the 1st clip in set 1 that i placed on the timeline are:
Image size 640x480
Frame rate 30
Pixel aspect ratio 1.0
Would you agree that these settings look about right, or would you still recomend the settings you previously suggested (for that clip from set 2)?
Also, just to complicate things slightly too, i have 2 further clips that i wouldnt mind fitting in that were captured using a different camera altogether. I was not going to use them because of the incompatible frame rate, but is it possible? It doesnt matter too much if its too much of a pain becausde they are only 2 clips.
Their settings are:
Video
Format                           : JPEG
Codec ID                         : MJPG
Duration                         : 3mn 2s
Bit rate                         : 16.3 Mbps
Width                            : 1 280 pixels
Height                           : 720 pixels
Display aspect ratio             : 16:9
Frame rate                       : 24.000 fps
Color space                      : YUV
Chroma subsampling               : 4:2:0
Bit depth                        : 8 bits
Scan type                        : Progressive
Compression mode                 : Lossy
Bits/(Pixel*Frame)               : 0.738
Stream size                      : 354 MiB (92%)
Title                            : FUJIFILM AVI STREAM 0100
I'll probably need further advice when the project is completed about how to ideally export the movie.
Many many thanks.
ps. This problem will not occur again, since i now shoot all my clips from 1 HD camera and with all the same settings, lol.
Just in case you wish to view the 1st clip from set 1 that i placed on the timeline, i have uoploaded it to skydrive:
