The Spirit Realm

Ok, so I am about to pl my paladin with my SK till around level 71/75 and a few hundred AA's. Will probably Max CA and CS and get him some Slay undead AA's and stuff. I want to get the Pally to around 80 so I can use him to pl my other account in Undead zones. I have a couple stupid questions if y'all don't mind. Someone was telling me about making sure I get self heal stuff. I am not sure what they are talking about are those AA's or Spells, and what would the names be? The other I was thinking of maxxing AA's would be:

CA/CS
Slay (and All Pre-Reqs)
Then All 2-Handed Associated AA's
Then probably the healing AA's.

Next, so I ever want to go back to Sword and Board, or should I stay with 2-Handers for the Damage?

Also open ears for any other advice, thank you in advance.

SK is probably much better pl class compare to Paladin. Paladin need a lot of AA, unfortunately like all hybrid you more or less need to invest in most of them to be really effective. For the exact AA just search for previous threads discussing this on the board. With the weapon under 80 I'd stick with 2 hander, only switch to 1 hander later if you intend to swarm.
