You got pretty good rolls I think.
As for a few thoughts,
#1 I'd have also gone with daggers for the aformentioned reasons.
#2 Your DM is more generous than many with HP. Now t I use "Living Greyhawk" style HP which is Max at L1 and the middle number on the die +1 which is 3 for a wizard. IIRC Living Realms may have done it this way as well for living play consistency It slightly benefits Wizard over other classes but its bascally fair IMO As also mentioned you do get a very valuable +1 on HP so at 1 you'd have 5 and at 5 you'd have 25. You might not survive your own fireball backlash so be carefull!
#3 The important stats do go up for a wizard. As mentioned 2e has aging rules and if you live that by the time you are old INT will have reached 18 and you'll have 9th level spells. IIRC there was no max for mental stat gain so you could even get a 19 at very old and be baleto auto learn all of the spells you could never learn back from the adventuring days, Also potions of longevitty and elixers of youth are not artifacts and if you can talk the GM into it, you can start making them when you can make potions as early as 9th level The former are pretty dangerous with a 1% cumulitive chance of reversing after each use though they reverse your age by 1d12 years at every go. The latter take off 1 year per use no bad effects but I am not sure they are in 2e. And yes you can give them to your buddies,
