If you have a ZIP utility, you could simply create a password protected ZIP-ed version to send.

If you have MS Word, you put the PDF file in a Word document and password protect the word document.  (Tools =>Options=>Security   - to set a password)

You could certainly use certificate based security if needed, but this is likely overkill.  How sensitive is your data? (ie, do you want to prevent casual observers from reading it, or do you want to make it difficult for another party to open in less than five days?)

If you have the full version of Acrobat (not just the Reader), you can directly encrypt/password protect a PDF file using either a password or a certificate.  The option is under 'Document Security' on the menu.  The person opening the file can be using the Reader-only version, they will be prompted for the password before the file will open.

Encrypt PDF software is a very flexible and powerful program, Encrypt PDF software allows you to encrypt (using standard 40-bit or 128-bit supported by Acrobat Reader 7.0 and up) existing PDFs, set permissions, add user and owner password. For example you can encrypt a PDF without to allow to print it. The button to print the file will be disabled in Acrobat Reader application, you also can encrypt a PDF allowing the user to read it only if he know the correct password.

Where would you turn off or on SSL?

Yes, you can encrypt files without SSL.  SSL is just one protocal for encrypting a communications channel, such as over the enternet.  SSL does not even apply as a method of encrypting files, however you could transfer files with relative security over a SSL encrypted connection.

Does all this  mean that with Acrobat pro I can send a file with a password and encrypt it WITHOUT using ssl and without using any other applications to accomplish both?

Yes, Acrobat Pro has this functionality built in.  If you already have a recent version of Acrobat Pro, you can do this already.
