Marius, don't feel bad about asking these things, it takes some getting used to. One example you might want to look into is gr-uhd/examples/python/freq_hopping.py, which is an example on bursty frequency-hopping data tx.
Proper tagging etc. for hardware control is not a trivial task. I've included the discuss-gnuradio mailing list (I assume you're subscribed to that, too) because there's a lot of people with experience in this are on that list. Do come back with more specific questions. Other than that example, I recommend reading the gr-uhd manual page (on the GNU Radio manual) and the page on tagged streams.
