Ok, so I translated the important parts of the Bf 109 E series, hope this helps:

Start-Up Procedure:

- Close canopy, open right window
- Gear switch to off
- Battery master on (pull switch behind seat, right side)
- Fuel cock open
- Throttle idle, set fueltank pressurisation to "entlüften" (=Ventilate)
- Pressurize min. 0,5 Atü via Fuelpump
- Crank well to load up starter
- Primer: 2-3 times (4-5 in cold weather), if engine is warm only 1-2
- Check prop clear, then insert key and select M1+2
- Pull "Zündverstellung and hold
- Pull Starter
- Relase both after engine starts
- Oilpressure must rise in 3-5 seconds to 6-8 atü, if not shut down immediately

Warm-Up Procedure:

- Open water radiator as required
- In cold wheather: close oil radiator
- Slowly increase rpm after oilpressure starts to drop until reaching 1000 rpm. Try to maintain oilpressure between 5 and 6 atü

Checks during Warm-Up Procedure:

- Check magnetos by switching the "Zündschalter" at different rpms, watch for smooth running
- At 1400 rpm check fuel pump: fuelcock in position P2 and P1 for 1/2 minute each, watch for excessive fluctuations of fuel pressure or rough running of engine.
- At 1900 rpm check electrical system: Switch off battery master, switch on avionics master. After check switch off avionics master and switch on battery master again

Before Taxi Check:

- Close canopy
- Check fuel cock open, fuel pressurisation on "ventilate"
- Open water and oil radiator
- Check battery master "on"
- Check engine instruments
- Set prop pitch to 12 o´clock
- Check gear (green lights), also check mechanical indicator
- Set trim to 0 to +1°
- Under high humidity conditions or temperatures belo 0°C turn on pitot heat

Taxiing:

- Flaps Up
- Keep water temp below 94°C
- For thight turns taxi straight ahead and apply throttle, then start turn by braking and throttle down.

Take-Off:

- Set flaps to 20°
- Start take-off roll
- After lift off gain speed until reaching best-climb speed (about 250 Km/h)
- Retract gear while accelerating (Set gear handle to "up", after gear is fully up the gear handle swiches automatically back to "neutral").
If gear handle does not switch back to "neutral" by itself pull the lever.
- Retract flaps and trim (both wheels can be turned simultaneously).

Note: If fuel pump fails emergency fuel pumping by handpump is NoT possible!

Flight:

Limitations:
Vmax
For flap operations: 250
For flaps fully down: 250
For gear down: 350
For gear operatiom: 220
For diving: 750

Best IAS for climb:
Altitude: 0 1000 2000 3000 4000 5000 6000 7000
Va (IAS): 250 243 236 229 222 215 208 200

- Attention! If fuel pressure drops below 1 Atü at high altitudes switch on fuel pressurisation (Switch to "Behälter unter Druck")


Prop Pitch Operation:

Set Prop pitch to keep rpm within the following parameters:

Increased time limited power: 2468 rpm at 1,45 ata
Time limited power: 2368 rpm at 1,35 ata
Increased power (non time limited): 2326 rpm at 1,3 ata


Oil Pressure and Temp limits:

Non-limited: intake 30°C to 75°C, exit 95°C
Short time: intake 80°C, exit 105°C
oilpressure: min 2,5 atü, max 6 atü


Water Temperature:

Close to ground at least 60°C

Max temp for altitude (in km):
0 2 4 6 8 10
100°C 95°C 91°C 87°C 82°C 78°C

Fuelpressure: min 1,1 atü, max 1,5 atü


Fuel indication during flight:
Good indication only in straight and level flight, if reserve light is on fuel is sufficent for about 10 min


Radiator operations:
For normal outside temperatures keep water rad half closed, if outside temp drops close accordingly.
After radiator operations trimming is required!
Note: The aircrafts speed is dependant on the radiator position. To archieve maximum speed open radiator only as much as requierd for safe temperatures!


Landing:

- Slow down to about 220 Km/h
- Set prop pitch to 12 o´clock
- Lower gear, gear lever resets to neutral automatically after operation.
If gear is not fully lowered after opreation set switch to "lower" again
Signal sounds if flaps are lowered while the gear is not fully down!
- Flaps full down (40°), trim the aircraft! (Both wheels can be operated simultaeously)
- Final approach with about 150 Km/h, take note that the aircraft looses speed fast if angle of attack is increased!
- If sight through windshield is not possible open and look through forward left window


Thats it for now, to tired to do the rest. Still missing is the abnormals and emergencies part. If you´re interested let me know, then I´ll do it tomorrow.
