How do I know what my rocket is capable of?

Huh??  This chart seems to imply that you can aerobrake on Kerbol. 

Well, it's also telling you how much juice you'd need to launch from the sun. So it's pretty safe to assume that those values and arrows are only theoretical of nature and for the sake of completeness.

I don't mind the juice from the sun, that's a perfectly reasonable number to include.  I'm just questioning the aerobrake arrows.

(And can you even launch from the sun anyway?  What's its surface gravity?)

 The launch values for bodies with atmospheres are either guesstimates or empirical results. It is possible to overperform or underperform in comparison, depending on your aerodynamics and launch profile.

All other values are calculated and highly reliable. Values to orbit are calculated by assuming infinite t/w and a Hohmann transfer to orbit. These values should be considered an absolute minimum for planning purposes.

 Transfers to SoI and beyond are computed using n-body math, and are thus a little overestimated. It's safe to assume that you can match or even better these values in practice with an ideal Hohmann transfer. All bodies are assumed to be coplanar and zero eccentricity, so a *specific* case may require a little more or less. The DV to match inclination is computed for the worst case scenario.

In principle it is possible to launch from 0 altitude on Kerbol, with ignore-max-temps turned on. I don't believe it's possible to achieve orbit without further cheating, though.

I'm questioning if a rocket could lift against it's surface gravity.

That's what I'm answering

We are getting off-topic here. OP is not launching from solar surface.
