How close will comet come to earth

[scatterbrain8]

I'm given the six orbital parameters for a comet and am asked to find how close it comes to earth, but I'm not sure how to go about this...

Should I calculate the position of the comet and Earth and the comet's perihelion passage? If so, are there equations for this type of thing?

The parameters are a=110 AU, e=0.995, i=89 deg, longitude of the ascending node is 180 deg, argument of perihelion= 0 deg and time of perihelion passage = 2008 March 21

I know it's vernal equinox, but not sure how to quantify the positions...
