Yes the whole temple part will be quite tricky with the low stats and all. Getting into the temple, luck manipulation FTW With a Katana you should be able to "floor" some of those guys in the doorway where I was stuck for a while in the uploaded video (And that's actually the only problem spot in this part mainly because of that stupid bow guy since he's blocking the doorway). You can maybe lure him away.
I actually think it would be better to restart the entire run and focus the most on other stats such as Ranged/Firearms and Celerity. You could even do short sidequests or ways to earn a little extra Experience Points along the way since you've got like 35/40 minutes or so of uhm, "spare time"... Whoa, whole new planning required
Also, I thought maybe it would be better not to spend the 2 points in the beginning to Dexterity, but instead it's maybe better to apply it to Strength (Or possibly Stamina? Or both 1 point?). If you just max Security and use Blood Buff you'll also get Lockpicking 10. I thought this would be more convenient since Blood Buff raises Dexterity until it's +5, so then you have some more Strength for any fighting parts (And/or a little more Bashing against bullets and such).
EDIT: Maybe a starting character with this:
Strength +2
Perception +1
Dodge +3
Security +2
Scholarship +1
Celerity +1
EDIT: I've just ran a bit through the game with the character I talked about above and you don't really need to add +2 to Security since you won't be doing much lockpicking (When you need to pickup the Horror Tape Part 2, there's a door which requires a lockpicking skill of 10, but it's just better to spend about 15 extra seconds to just go the other way around instead of upping the lockpicking skill that high). Better spend the other point on Firearms or Melee. I'm saying "or Melee" because the Utica didn't really have too much impact on Ming Xiao (I had a Ranged skill of 7 at the moment I faced her). So maybe it's better to upgrade Melee and just go at it with the Katana (Or bare hands possibly...), I don't know yet about that but I'll start a new character and try it out.
I've found another nice shortcut in the sewer parts after Andrei. There are some locked doors that you can still open from the locked side, and this particular door makes for a bit weird kind of shortcut. I shall make a video of it so you can see why I say weird But it skips a nice portion of the sewers. Here's the video.
In case you're wondering, I wasn't able to open the door in the sewers in Hollywood, otherwise you could skip a big part and immediately go to this shortcut But I shall check it a little better in my next playthrough.
Couldn't find a way to open the little door to reach Gary early though, seems not possible :-/ Unless you can maybe somehow glitch a little through a wall in some way, then you could probably activate the door (Checked it with noclip) but I couldn't get it done.
I also picked up the Gladjum just before Gary, it gives a little longer duration for the Disciplines but I'm not sure if it's really needed. I don't think so actually.
Oh and yes, the temple part is pretty tough but it's doable.
EDIT: There was another little trick by the way. After you've visited Isaac in Hollywood, a girl (Forgot her name) starts talking to you on the streets right? Just before you trigger that conversation, shoot with a gun and she'll be scared and won't start talking to you (You'll get a Criminal Violation but it's possible to not encounter a cop so you can safely enter the game shop). She won't talk to you ever, when you run past her a couple of times while doing quests, she will run towards you but won't say anything.
