Personally, I prefer editing .csv with notepad++. It's a lot cleaner to look at and it also works great. However, sometimes you might prefer an actual "table" view or something like excel to understand it, so either try excel (while a lesser choice, open office also works) or CSVed.
EDIT:
Else, good tutorial. Though some settings in the dbc you provided differ from the dbc on the wiki - might be worth looking at both to see what you rather think and afterwards share your experience.
