They theorycrafted a team build I believe, he has like a wand templar with power siphon and conduit(gives power charges to every allies around) so I assume the other people in his group also do. As said though, you have rare drops Orbs of Regret that give you a full respec and you get a bunch of respec points if your spec isn't too bad and you can rework it with only a few removal, so it's no big deal. Because of that, it might be a good idea to dump heavily into defensive skills at first to get a good buffer for HC deaths, and then remove some of it if you don't need it anymore(for example life nodes before you take CI).
As for the zones to grind, based on what kripp was doing, it's The Ledge(the zone after the underground passage with a bunch of skeletons), West Forest(suicide zombies and whatever) and Fellshrine ruins(tons of slow moving undead). I'm not too sure why these specific ones are chosen besides Fellshrine which is obvious though, the Ledge doesn't seem particularly heavily populated and it kinda sucks if using a fire build(but then again most top builds aren't fire cause shock and freeze are better than burning) and West Forest doesn't make any particular sense, do suicide zombie mobs give xp when they die? I assumed only if you kill them, not if they suicide, which would be pretty shitty xp actually. Doesn't really look any better than Crossroads or hell Fellshrine which seems to be about the same lvl iirc.
Been playing a char in that race just for fun, made a summoner, leveling slowly but don't really care just wanna have fun, the great thing imo about PoE vs TL2 or D3 is that Hardcore isn't as punishing. If you die in HC, your character gets transferred to softcore instead of being deleted(granted in TL2 you can tinker with the save files and just cancel the death but that sucks). So even if you die to pure bullshit like desync/lag, your time investment isn't completely wasted, you can still play the char, just not in HC anymore. I really like this system.
