That is able to do (tw dunamenw poihsai). Dative case of the articular participle (present middle of dunamai). Paul is fully aware of the greatness of the blessings asked for, but the Doxology ascribes to God the power to do them for us.
Above all (uper panta). Not simply panta, but uper beyond and above all.
Exceedingly abundantly (uperekperissou). Late and rare double compound (uper, ek, perissou) adverb (LXX, I Thessalonians 3:10; I Thessalonians 5:13; Ephesians 3:20). It suits well Paul's effort to pile Pelion on Ossa.
That we ask (wn aitoumeqa). Ablative of the relative pronoun attracted from the accusative a to the case of the unexpressed antecedent toutwn. Middle voice (aitoumeqa) "we ask for ourselves."
Or think (h nooumen). The highest aspiration is not beyond God's "power" (dunamin) to bestow.
