About your First Question
Assuming that what you're trying to achieve is to toggle the "UV Grid" option

You effectively have two options:
The easiest one is to execute CallCommand(170776) (you can find the command ID in the Script Log)
The more involved but also more flexible way is to find the UV settings scenehook and go through all its branches (or may be not all of them, depending on what specifically you want to achieve). Please find the C++ and Python code snippets below.
Cheers,

C++ commanddata execute function code snippet:
Bool MyCommandData::Execute(BaseDocument* doc, GeDialog* parentManager)
{
const Int32 ID_UV_SETTINGS_HOOK = 1053309;
if (!doc)
return true;
BaseSceneHook* sceneHook = static_cast<BaseSceneHook*>(doc->FindSceneHook(ID_UV_SETTINGS_HOOK));
if (!sceneHook)
return true;
maxon::BufferedBaseArray<BranchInfo, 20> infos;
sceneHook->GetBranchInfo(infos, GETBRANCHINFO::NONE) iferr_ignore("GetBranchInfo");
for (BranchInfo& info : infos)
{
if (info.name != "UVSettingsBranch"_s)
continue;
GeListNode* viewSettings = info.head->GetFirst();
while (viewSettings)
{
GeData value;
viewSettings->GetParameter(CreateDescID(UV_SETTINGS_FILTER_SHOW_GRID), value, DESCFLAGS_GET::NONE);
Bool valueBool = value.GetBool();
value = {!valueBool};
viewSettings->SetParameter(CreateDescID(UV_SETTINGS_FILTER_SHOW_GRID), value, DESCFLAGS_SET::NONE);
viewSettings = viewSettings->GetNext();
}
}
EventAdd();
return true;
}
Python script code snippet (special thanks to @m_adam on this one):
import c4d
def main() -> None:
sh = doc.FindSceneHook(1053309)
for branch in sh.GetBranchInfo():
if branch["name"] != "UVSettingsBranch":
continue
viewSettings = branch["head"].GetFirst()
while viewSettings:
viewSettings[c4d.UV_SETTINGS_FILTER_SHOW_GRID] = not viewSettings[c4d.UV_SETTINGS_FILTER_SHOW_GRID]
viewSettings = viewSettings.GetNext()
c4d.EventAdd()
if __name__ == '__main__':
main()
