1. Morse Code is an on-off keying. The vectors represent each dot bit time as a 1 and each space bit time as a 0. To transmit this data, the RF carrier is turned on and off with these vectors. In the example, the Signal Source block simulates the RF carrier and the Multiply block keys it on and off. Note that in my github link I have revised the filter to create a better keying waveshape.

2. Study the Tutorials and the Sample Rate Tutorial in particular to get a better understanding of setting sample rates.

3. Now to address your desire to translate vectors into FM, I am guessing that you are looking at RadioTeletype (RTTY). To do that, or a similar application, you must key two frequencies with the vectors. For RTTY, the standard tones are 2295 for Mark (1) and 2125 for Space (0). There are various modulator blocks to use, or you could use a "brute force" method with two signal sources.

GNU Radio allows you to experiment with various arrangements easily. So study the Tutorials and try things out!
