HP -> use item ability bug on maximum HP increase item ability. This is done by turning the item ability into a 2 level unit ability where level 2 gives less health (usually 0) than level 1. By adding the ability, setting it to level 2 and then removing it you will notice that the unit has gained (or lost, depending on settings) maximum health permanently. This is the best way to do it as it is leakless and fast.
Damage -> not sure if item ability bug works for this. Use damage tomes (yes you can temporarily give a non-hero an inventory, give it a tome and remove the inventory). Do remember to remove all tome items if used since they are not automatically removed.

There are many useful standard libraries you can use to do the above. Although I think the people who wrote them were vJASS/LUA freaks so they might not work properly anymore.

I would be careful with values like that. Usually 10 damage corresponds to 10 hp more lost. Since they usually fire more than once, this is a drastic statistical imbalance. Additional HP should be considerably larger than damage for this reason. You may also want to limit how far a unit can be upgraded like this to prevent a single unit becoming rigged. You may also want to award kills to nearby friendly units in the case that a unit is at the limit to prevent kill wastage.
