I would switch the polearm a nd 1h wpf's. Put the emphasis on 1h weapons, because the lance on horseback doesn't require too much wpf, really. It's the 1h weapon, used on foot with a shield, that you'll notice the wpf difference with. If you wanna be able to fight effectively with it on on one, you'll want about 120-130 wpf with the 1h weapon.
I saw someone else post a polearm/1h build. The WPF was:
Polearms: 90ish
1H Weapons: 120ish
I myself put all wpf into polearms, and do as Gondemar suggests. If it weren't for the slot issues, i'd fight as a hoplite/cavalry guy, with heavy lance, shield, and spear.... but spear is 2 slots, alas.
