1) do run in "Hotlap" mode, as it will tell you if your lap is valid or not, and it will also tell you what your best lap of the session is.
1:35 is feasible - you have it all here from what I see!
Your main problem seems to be consistency / repeatability - it seems that you are pushing a bit too hard at the moment.
My recommendation would be that you try running a few laps within a few 1/10th, 0.5 second. Try 1:37 ot 1:38, do 10 laps without outbraking / power understeering, smoothing your inputs.
Checking the replay: I use chase view or heli view for the lines, chase view and press F to see the forces on the tyres. There you can see when you lose grip and when you lock tyres. Use F2 + F3 to change the replay speed.
Lap 2: Locked tyres - outbraking yourself. Brake 10m early to get consistency, speed will come later. You had to release the throttle mid corner - no good.
Between T2 and T3 you slide most of the laps - correct your line to reduce that, as it is just before the long straight so it will cost you a lot of time. For this lap you were nearly there, good use of the kerbs, try to apply the same line each time.
T4 end of straight: apex too early, plunge further and apex later will be more efficient.
This turn cost you a lot of time in this lap! You also over-revved the engine into 3rg gear, probably causing damage.
T5-T6 ok, but missing speed due to T4.
T7: throttle too early --> understeer, missing apex and forcing you to lift.
T8: wrong line, probably due to dirty tyres.
Lap 3
T1: lockup, understeer and missed apex. Brake 10m earlier and decrease braking pressure as you slow down to prevent lockups. Do not apply throttle before the car is pointing in the right direction and while in full lock.
T2 -T3 ok but missing speed due to above
T4 certainly killed the engine again (3rd gear). Throttle on full lock again, before the car is stable, causes massive understeer-->forcing you to lift, big time loss.
For the rest:
Lap 4: good first tun! no lockups, good apex speed. Ruined by T2 - too much kerb though.
Good line in T5 - T6.
Lap 5: Good T2-T3, minimum slide. Despite a lockup and understeer in T1 the first split is good, showing the importance of T2-T3.
Lap 8: good first split, T1 with a later apex carried more speed through the chicane.
Overall decent lap.
I stopped here
You seem to use too much steering lock and have a tendency to turn in too early from what I have seen, compensated be power-understeering. Try it a bit smoother (slow in - fast out) and I'm sure your laptimes will drop. Concentrate on consistency first, then speed.
Good luck!
