It sounds like your HMAC-SHA1 signature generation is not correct. I would recommend going to the most basic examples in the OAuth specification ( best walked through here: http://hueniverse.com/2008/10/beginners-guide-to-oauth-part-iv-signing-requests/) and make sure you can create the same signatures as the examples -- without ever making an actual API call -- before proceeding further.
Once you are sure your signature generation algorithm can handle the basic examples in the specification, move on to Twitter-specific requests. Attempt exotic requests, like status updates with UTF-8 characters and spaces. Also important to note that the OAuth specification requires an oauth_callback to be provided on the request_token step, regardless of whether you've pre-specified it in your application record or not. If you're not doing a URL-based callback, you should be providing oauth_callback=oob.
