I got to eeloo without using launch windows or stuff.Everything I used was a normal lander used for mun missions,a tug with LV-N,and a lucky shot when eeloo was nearing its closest point to the sun.It's actually hard to get an intersect with eeloo while it's closest to the sun,so wait while eeloo is still far away from that point. In short,use LV-N and maneuver nodes. Moho is pretty hard,if you try to get an intersect at periapsis,you will need lots of delta v to slow down ship to get into orbit around moho.But it's actually not as hard as people say.
