That is correct, 35mm = 52.5mm and 50mm = 75mm. Do you have the 18-55mm kit lens? Set it to 35mm for a while and then 50mm for a while. Same angle of view, just the prime lens will give you better performance, especially in low light situations.
For random/street stuff the 35mm is plenty tight. It's all preference. Some prefer the longer 50mm, I personally feel the 35mm is tight enough, especially for tight spaces. Just look through both and make your pick.
For portraits the primes will make due but they are not portrait lenses, so to speak. You can still get great pics of people out of them.
The only one who can tell what you would like is you in the long run. Try both out, or even other lenses.
@Rampo - I agree with @Adelphos. I would start with either a 35mm or 50mm prime. For street photography, I would probably lean a bit more towards the 50mm which will give you a longer focal length compared to the 35mm. This will allow you to frame subjects at a farther distance compared to the 35mm. Happy shooting!
