This depends what you want to achieve. Use gr_modtool help add for more 
advice.

More modular is usually better.

How good is your C++? Maybe it's worth brushing up the basics first, or 
perhaps you might consider writing the block in Python.
Also, I recommend looking at some of the blocks in GNU Radio as 
examples. I didn't fully understand what your objective is, but there 
are PLL blocks which you can have a look at for input.
