Have a look at some of the bass charts on my site. (Go to the basslines section). They are fairly stock standard. You don't generally include fingerings unless you specifically want something played somewhere - for example if you definitely want an open string.
I think that most of the newer techniques are really too recent to have resulted in standard nomenclature - so if you have to notate something out of the ordinary like a double or triple pop, then you have to describe it in the chart. No-one would be able to read it otherwise as even if there is an existing symbol for it, it's unlikely that the player would recognise it or be able to read it.
Things like T, P, S and H are pretty standard though, along with X for ghost notes on the appropriate strings.
