The following site is great as it also includes pronunciation.

Grammar Points:

Firstly, as in all languages, w e must understand the grammar. For the Bahasa Indonesia ( i.e. Indonesian language):

Adjectives always follow the noun, e.g. beautiful car - mobil cantik.

Word order is usually subject-verb-object (e.g. Saya(I) mau(want) makan(to eat) nasi(rice) - means I want to eat nice; and the personal pronoun goes after the noun (mobil saya is "m y car")

Respect is shown when addressing, so the custom is to address an older man as "bapak" or "pak",  an equal/younger man as "mas", an older woman as "ibu" or "bu", younger woman as "nona", married woman as "nyonya".
