I am hoping to find some actual Punic to use for quotes. Here's a passage from Plautus, Poenulus, Act 5:

Hyth alonim vualonuth sicorathi si ma com sith, Chi mach chumyth mumys tyal mictibariim ischi, Lipho canet luth bynuthi ad ædin bynuthii. Birnarob syllo homalonin uby misyrthoho Bythym mothym noctothii velech Antidasmachon. Yssidele berim thyfel yth chylys chon, tern, lyphul Uth bynim ysdibut thinno cuth ru Agorastocles Ythe manet ihy * * chyrsæ lycoch sith naso Byuni id chil luhili gerbylim lasibit thym Bodyalyth herayn nyn nuys lym moncoth lusim. [Exalonim volanus succuratim mistim Atticum esse Concubitum a bello cutim beant lalacant chona Enus es huiec silec panesse Athidamascon Alem * * induberte felono * * buthume Celtum comucro lueni, at enim avoso uber Bent hyach Aristoclem et se te aneche nasoctelia Elicos alemus [in] duberter mi comps vespiti Aodeanee lictor bodes jussum limnicolus.
According to Perseus, the first sentence "Hyth alonim vualonuth sicorathi si ma com sith" means "I worship the Gods and Goddesses who preside over this city" which is a ok quote.

Here is a link to an excellent site on Latino- and Graeco-Punic texts from North Africa but is highly technical.

There's also a book, Late Punic Epigraphy, By K. Jongeling, Robert M. Kerr, which is the current state-of-the-art on Punic inscriptions, but I have only seen it on google books preview.

There's also some interesting work being done at the Bavarian State Library in Munich, who are in the possession of hundreds of pieces of Sabaean miniscule script, like this:



But I haven't seen any translations as yet.
