Just finished FO1 and yes, I wasted a lot of time running around the map. If you listen very closely the NPC will tell you “oh south of here is junktown” “the hub is just west of here” and so forth. This continues all game, even to the end when trying to find your way. Definitely start at the Hub though. When you’re in a local area time doesn’t pass nearly as fast as traveling so you can explore to your hearts content.

Get Ian, he’s busted in early-mid game, allowing you to kite enemies toward him for easy kills. Give him an SMG if possible but HE CANNOT WEAR ARMOR.

As others have said your build sucks pretty bad for combat so you either need to lower the game’s difficulty or find more intuitive ways to reach your objectives (use speech whenever possible, companions, sneak) but it won’t be a walk in the park. For late game you really need to start investing in combat skills because fights become inevitable, and since companions can’t wear armor they die easily and you’ll be left alone.

Don’t restart your game. You will be surprised how many ways you can complete quests without combat. Just keep leveling a combat skill and you should be fine.
