I hate to belittle Portugues, but it sounds like Spanish with an accent, not a separate language. There are languages on the Spanish mainland that are more distinct from Castillian than Portugues.

There are a large number of cognates between Portuguese and Spanish... I've read 85% in some cases.

Don't let that fool you into thinking they are not separate langauges. If you don't believe me, come here to Rio and try to speak Spanish with people. Next, take a dictionary and look up words for things like fork, spoon, and knife.

Knowing Spanish speeds up learning Portuguese bigtime. I became conversational, including telephone conversations, in less than 3 months.

Now, I have a very hard time switching between the two languages. It takes a few days to get from one to the other without thinking very hard.

Hector is correct; while there's a large overlap in cognates, the languages are quite different, and anyone trying to learn Portuguese by trying to translate everything from English to Spanish will be frustrated. The differences are especially stark in pronunciation, as there are many nasalized vowels in Portuguese that don't exist in Spanish.
