Don't do that quest first. The quest is close to impossible if you do it as your first quest (the stuff you do in the base I hardly consider them quests). Go do the outpost quests, along with finding the watch (you'll get the quest as you head out there) and the one to shoot the crossbow bolt into the rathound. After you complete those quests and basicly, clearn that whole part of the map which is small, you should have at very least an SMG and probably a grenade, if not you can either craft one or buy one, they aren't so expensive. Your third quest is going into the GMS compound (third becuse you'll get one to also catch hoppers which is not hard, mostly boring but I suppose it teaches you about hunting and stuff) and when you do, you do the package run since you head in the same direction.
I'll even give you a tip. There is a barrel on your right, stand to it's side and wait. Behind the enemies there are rathounds which will ocasionally come close to them and aggro on them so they will turn back and fight them. Then you walk to the metalic grades on the ground somewhat close to them and throw the grenade, a decent toss will start all 3 enemies at half health and so long as the rathounds are still alive they should keep attacking them until they are dead, worst case scenario is 2 of the 3 attacking you with rathounds still alive. At this point it should be pretty managable... If you have stealth and just don't want to fight (which I don't advise since you like loot and XP right?) then after the rathounds aggro them you can stealth behind them and enter that 2 square exit to the left, it takes you to the lower underail. Basicly it's just a sort of a large map but with narrow passages and multiple exits which are also scattered all through that piece of the map so you can bypass that fight entirelly. Of course that is only half a solution since you'll eventually need to come back and have to kill them anyway, by that time the rathounds will be dead to aggro them again so you stealth safely.
Lastly, not exactly a protip but if you put 1 point into every abillity then in my opinion, you're not well rounded, you're just bad at everything. My advice on character building is, at least 9 str for mellee type of guy, at least 9 perception for guns type of guy or at least 9 will for a psiker... You can then mess around with what you want to do relativelly to your other statistics, usually you can get away easly with getting one attribute at 3. As a psiker I do that to my strength because I can just use crossbows which require no strength to use and are cheap ammo, besides they don't really spend much ammo so it's a pretty cheap run so to speak. A gun guy can get away with 3 will easly as you don't need to delve into psionics. A mellee guy depends on how you wanna build it really.
