First, I would burn something to see if it works. Look at the bottom of the wodim man page for examples of the process. Then dd the cd back to a file (ex - dd if=/dev/cdrom of=copy.iso). Then ls -l and compare sizes and do a diff if they compare ok. Then let us know.
Btw, your options *look* correct, just thought I'd let you know of those examples. Also about a week or so, we had a discussion about scripting cd verification - some of that might be worth a read. I don't really use k3b so can't really offer much advise there. But, once you can burn something from command, k3b should be easy enough to figure out.
