Advice for taking up asphalt to create backyard

The driveway at my house extends past the garage such that the entire back "yard" is paved over with asphalt. I plan to remove all of the asphalt aside from the driveway to create space for a deck and backyard. Please give any feedback or advice on this plan in case I'm missing something:

1. I called 811 and confirmed no buried utilities in the backyard. The electric to the garage is supplied by an above ground hanging wire.
2. I am renting an asphalt dumpster, and then will separately rent a dumpster for the compact stone
3. I have an SDS Max hammer, a crow bar, a wheel barrow, and a shovel. I plan to break and pry up the asphalt, and get it to the dumpster via the wheelbarrow. I estimate there is about 5-10 tons in the back
4. I plan to use the SDS Max hammer to cut a semi-straight line between the inside corner of my garage to the inside corner of my house. That will make a relatively but not perfectly straight edge for the yard, while keeping a full size driveway for access to / from the garage
5. I plan to leave about 1-2 inches of asphalt around the foundation of the garage to minimize any risk of termites
6. I plan to leave an area of compact stone about 10×20 feet directly behind the house so that sometime soon I can build a wooden ground-level deck over top of it
7. I will have about 5 cubic yards of dirt delivered and grade it down away from the house to replace the asphalt and stone
8. I will install a gutter on the low side of the garage roof to prevent erosion in the soil around the roof
9. I *might* install PVC and / or french drains through the length of the yard (i.e. from the deck to the rear of the property, where there is a large slope into the next property which is an empty lot) prior to installing the dirt. The PVC would be to carry the water from the downspouts out to the rear of the yard and away from the foundation. I figure that would be easiest to do while I have the yard dug up already
10. I will plant shade tolerant grass seed in the fall to try to get some grass growing under the shade of the tree. I know that I might struggle to get grass around the roots directly below the tree but I'm hoping for some semblance of a small lawn between the deck and tree.

Anything I missed or big issues I should look into?
