You'll first need to convert your clips to DV PAL or to Pro Res Quick Time files. MPEG Streamclip can do that for you. If you haven't used this app before, check out Nck Holmes' tutorial.
Once you convert it all to an editing codec, FCP can automatically determine the correct sequence settings. Just import the converted clips and drag one to the Time Line. when it asks whether you want the sequence to match the clip, choose "yes" and you'll be good to go for the rest of the clips.
I was looking at the spec sheet for that camera-- I can't even tell what it shoots, other than mpeg2. Is it hi def, Standard def? What?
At any rate you'll need to convert to a format that fcp understands. Use mpeg streamclip: free and indispensable application, to convert it to something fcp understands. Prores LT is probably perfect.
Import those files into fcp and drop a clip into a timeline. The program will ask if you want to conform the sequence properties to the clip. Say yes. Edit happily. you can export to anything you'd like.
Presuming that your footage is already in FC and it is playing properly.
Create a new sequence
Drag, insert or overwrite a clip into the sequence.
If the preferences have not been tinkered with you will be prompted to have the sequence settings match the clip settings. Click yes and then the sequence will match your footage.
