Can I decrypt an RSA algorithm using only the message I am wanting to decrypt, an "e" value and a "n" value?
You have the public key. The whole point about public key cryptography is that the message is encrypted with the public key and must be decrypted with the private key, which you don't have.

The public key is not a secret: it is distributed publically so that people can encrypt messages for its owner. If you could decrypt the message knowing the cyphertext and the public key, RSA would be completely broken, because then anybody could decrypt any message. If anybody knows how to do this, they're keeping it a secret.
