| Ghost notes don't have a pitch, so it's quite common to notate them as an X on the note repesenting the string they are played on (the mass of the string does make a difference to the sound, even though you can't tie it down to a specific note).
I suppose (0) is one way to show this in tab, although personally, I'd probably still use an X instead. Try different ways of approaching it, listen to the record some more and recognise that, ultimately, it's your decision.
Even when playing covers, I often don't put too much work in trying to sound exactly like the originals for a number of reasons:
1) I'm not in a tribute band - people have come to hear me and not a clone of Tommy Shannon (or whoever else!).
2) When you're covering a range of different songs, it's very unlikely you'll be able to replicate all the nuances of the different instruments, amps, effects, strings and playing styles the bassists were using on the originals (even when just working on stuff by one band or even from one album!). Perfection is good but time is limited!
3) Unless everyone else in the band is also nailing their parts, I think it's more important to play with them rather than ignoring the rest of the band in order to get the bass part exactly right.
Of course, if you're doing this just for private study, then push forward for as much detail as you can!
