good job getting it done. rebooting would have been risky, no fun if you're paying labor.
1. the original axles would have lasted the life of the car
2. they may or may not have made noise - they are often quiet once cleaned and regreased. i have a set that i beat to snot without boots for thousands of miles, offroad, towing thousands of pounds up 10,000ft Colorado mountains, coming back east they made noise and vibrated so bad that i had to constantly change speeds to stop the madness/shaking and stuff them with grease by hand at ever gas stop to make the 2,000 miles home. i beat the snot out of them. rebooted them and they're still on my vehicle today - which is also lifted 2", stressing the joints even more.
probably not a good gamble for someone paying for labor, but so far i and others have done it a bunch without issue.
the Subaru boots last much longer than aftermarkets. i've routinely had aftermarket boots fail in 30,000 miles.
the best replacement option is to buy a used OEM subaru axle (green inner cup) and reboot it with Subaru boots
aftermarket axles have terrible issues - they routinely have issues at low mileages, including right out of the box. 10-25% have issues right out of the box, 50-75% (some people say 100%) have issues within a few years.
