I would suggest Jewels of the Sun/Happier times for skill haste and Plunder Pals/Valiant Crown/Enchiridion for skill damage. Choose whatever matches your playstyle the best. If you focus on skills to deal big hits, go for skill damage. If you want to get energized as quick as possible, go for skill haste. You can also go for strength up wyrmprints like Crystalian Envoy/Evening of Luxury if you focus on regular attacks and force strikes. Personally I'd go for skill haste as Lucretia gains strength up buffs with energy levels and she only has one damage dealing skill (excluding weapon skills).
