I don't do too much with grading, so not sure on the what going into it, but I would stick to dirt rather than gravel. you want grass there too.
You will need to be careful adding too much soil against your house for 2 reasons. 1. if the new height gets to close to your siding you can start damaging that, which could also allow any water to go over your concrete wall. assuming the concrete stops at the siding. 2. even if you build up the dirt, that crack remains and more dirt increases the amount of water stored (the dirt will act like a sponge). so the water trying to get away will still find that crack. if you get rid of the ponding it shouldn't be much of an issue, but if you get several days of good rain you will still see water seep in that crack.
and beyond creating a slope you still need a new low point and imo its better to remove dirt than try and build it artificially. you want to give the water a place it can other than towards your house.
I would still look at fixing that crack somehow, and mostly from the outside. if its a solid concrete wall you can probably get it patched/patch it yourself. there should be some self repair kits out there. You could try sealing it with new concrete, but often that doesn't bond too well, so you probably need an epoxy (flexible) sealant. even if you don't fix the grading sealing the crack should cut down a lot on the water you see. the reason to seal from the outside is to keep any water from getting into the wall. where if you patched the inside, you wouldn't see water coming out, but the concrete around would still be absorbing the water that got in from outside. where a seal from outside keeps the water out.
all jmo.
I plan to put some hydraulic Crete in tomorrow.
