The MAX7000 datasheets mentions some industry standard programmers (e.g. DATA-IO) supporting it. I presume there exists a specification of MAX7000 programming algorithm, but I wasn't yet aware of it or any DIY programmer designs. Today, MAX7000 and MAX3000 are legacy devices and will be hardly supported by new tool developments.

Requirement of bypassing depends on the involved signal speed and amount of simultaneous switching outputs, I believe. As a standard measure, I would place one bypass capacitor at each VDD pin. I have however an old design with a socketed MAX7032 in PLCC package on a two layer board that works well with a single bypass capacitor.
