Melvin,

Have you found the datasheet for MC13145 at;
http://ebus.mot-sps.com/ProdCat/psp/0,1250,MC13145~M928145,00.html

and the datasheet for MC13146 at;
http://ebus.mot-sps.com/ProdCat/psp/0,1250,MC13146~M928145,00.html

You may already have or will notice that not all vendors supply recommended land patterns.  I could not find any searching Mot's site.  It is very annoying, to say the least.
Even IPC-SM-782 has no specs for a QFP 4x4-(for ANY pin count) or a QFP 7x7-48.  Though IPC-SM-782 does provide min solder joints which may or may not be of help.
I do not know if wave or re-flow opens another can-o-worms.
