That sounds right to me too, nice catch. About the aorist, I believe that both pavisi.m and paavisi.m are correct alternatives. As you know, there's an optional 'augment' short /a/ that can be prefixed to aorists. If there's another prefix the augment goes between it and the root. pa+/a/+vis+i.m. (Ven Pandita: _Verbal Endings and Conjugated Verbs_ p. 5.)
The example provided by Ven Pandita there displays a common sandhi that can disquise the augment and make the basic form of the verb difficult to guess. After the prefix /pati/ the augment /a/ leads to pacca. pati+a > patya > pacca. The common form paccassosu.m (they assented) is a case of this. pa.tissu.naati is the present tense form which you can look up in the PED. In the aorist this goes to pa.ti + a + (s)so + su.m > pacca+sso+su.m. (note: su > so, as per Pandita page 32). Luckily this aorist is so common that the PED has special entry for it that refers back to the main entry.
So a good rule of thumb for beginners is: when you see /pacca/, consider the possibility of pati+a (or pa.ti + a).
Of course this combination can arise in other ways, such as paccate/paccati, the passive of pacati 'cooks'. Here it's the passive marker /ya/ that causes the sandhi. pac + ya + ti/te > paccati, paccate.
