Ineed some on independent and subordinate clauses plz and you

An independent clause is found in a compound sentence and occurs when each clause can operate as a complete sentence in it's own right.

A subordinate clause adds information but does not serve as a sentence in it's own right for example, it relies on the main clause within the sentence to make sense.

The sentence you construct would be a compound sentence and would read:

obama was told in early july 2004 that he was chosen to deliver the address, and he largely wrote the speech himself, with later edits from the kerry presidential campaign.
