What you choose really depends on what you want to do
If you intend to raid on your zerk, and want a 6 box to support you in farming and group content? Raid geared zerk can tank group content just fine. Shm, bard, 3x DPS
Want to kill harder stuff like old raids? Then you need a plate tank and a cleric. So tank, shaman, bard, cleric, dps. You'll need to invest hard in your tank to keep them geared enough to tank better than your zerk.
Don't intend to raid at all and play the game in group gear? Plate tank and cleric will be essential. Consider getting a chanter instead of either the bard or shaman, better mez really helps a group geared team.
Since you said
> Doesn't need to be min max
Then it really doesn't matter though, play what's fun to you. I think high dps is fun and would probably pick option 1 if I had a dps main.
But the 6 boxer cookie cutter setup of tank/clr/brd/shm/dps/dps is cookie cutter for a reason, it's really good
