Yes, when when system settings is added, deleted, changed etc. starting with a fresh guisettings.xml is recommended. Otherwise you might run into trouble with "invisible" or old settings and have conflicts.
Another thing;
Gpu_freq will set all gpu clocking including core_freq. Core_freq has a big impact on performance in XBMC.
If you still want to downclock some gpu freqs I would recommend that you do that separately.
For stability, if you use the same pll (default) they should have a relation with an even integer such as 1/1, 2/1 or 3/2 (for example, good numbers if gpu clocks are set to 250 is 250, 500 or 375). So with gpu_freq 175, 350 would be a good value for core.
However, if you don´t use analogue audio you can use a spare pll for core_freq with the following setting and this relation will not matter:
In other words, if you set this you can set core_freq to whatever without stability (or performance) issues (unless you set it to high or to low of course).
On high overclocks you might need to overvolt to get it running (and most important, have a good power supply where voltage does not drop to low), but have in mind that if you use force_turbo + overvolting you may set warranty bit.

On the other hand, maybe you are happy with your setup and already have tested different settings.

I honestly don´t know Xbian, but I doubt very much that they have the same structure as Raspbmc, so no it will not work.
