there are two ways to launch control with advanced timing and retarding timing, retarding (negative value) give you a spark after TDC, advancing the timing give you spare before TDC, timing is a fun tool as your gas/air flame expands you'll make power at different timing points and every engine is different, as for launch control I'd set the rev limiter to about 4300 rpm and the activation RPM about 4100, and -25 for timing, you can add fuel as well, the hondata help file says adding fuel will heat the exhaust, but when reading another document it stated that adding fuel would cool the mixture kind of like how you increase fuel to reduce knock under boost, as for setting the vtec point, in parameters there is a tab call VTEC, it has a low and high manifold RPM, for ease of use just keep these RPM's identical, and set your activation TPS or throttle position at about 50%, since you'll only wanna be in vtec when WOT, also don't lower your VTEC point to say 4000 RPM as this will probably not yield any power gains, the whole point of vtec is to allow more air to flow through the motor, but more air at low RPM without a turbo is useless and this is why there is a non-vtec lobe so basically your motor won't get any faster between 1-5000 RPM, but changing the vtec point from say 6200 to 5300 could potentially increase the right amount of power in that little bit of rpm range.

I advise reading the help file in all areas of the parameters section of smanager, don't be lazy do some reading, if you don't understand what it is you've read thats a different story and then i'm sure more people will be willing to assist.
