Ill crank up the engine in a few days. What steps should i follow before that?
Oil to be used at temps 30C - 35C? What oil pressure will i see after this?
After first start for how much time i need to start and idle it?
good luck with your build!

Turn the crank with a socket before starting the engine. also. did you spin the crank after assembling the shortblock to make sure it spins freely and dosnt feel like its to hard to turn by hand?

I have to first take out the plugs, and disconnect the injectors and crank the motor for 7 to 8 secs and the fire up the engine.
Mineral based oil for first start up and change ? and synthetic for the brake in ?

It is not so much the fact that it is difficult for a novice. The engine is held together with nuts and bolts -- trained monkeys can turn nuts and bolts and I would not be surprised if you could teach a monkey to take a head off a block.
The value in paying an experienced shop to rebuild your motor is in the fact that they have built XX or XXX of these engines and countless others and know what to look out for when putting them back together. Again, the difficulty is not in disassembly or even reassembly, it is in the requirement of measuring tolerances, clearances, judging surface finishes, etc.
If you have someone experience who can give you input I would go for it, but from the sounds of it you do not, and furthermore you have not done the reading/research to have all the knowledge yourself.
My two cents...

UPDATE!
started the car for the very first time after rebuild.
Car idling at 800 RPM
Water temperature 87C
Oil temperature 93C after an hour
Oil pressure at the start was around 4 BAR later dropped to 1 BAR
Fuel Pressure 38 Psi

Looking for 6 puck clutch and pressure plate kit.
Which one should i opt for ? ACT Xtreme or Spec R ?
or ACT clutch with stock pressure?
Also looking for a good wide band. Reviews about NGK Afx or ECM Lambda Pro ?

Update *
After the rebuild the car experienced a vibration problem, it started to occur at almost around 2500 rpm and vibrated till 4000 rpm. On diagnoses we found out that it was the balance shafts that were causing all the vibration.
The parts that i installed are.
Balance shaft removal kit, [ stub shaft ]
Fluidamper
TIMING BEARING
Tensioner bearing

For stub shaft installation
- Balance shaft can be taken out and also the balance shaft bearings by just opening the front and timing side foundations, no need to take the engine out if you find it difficult.
- We first installed the Damper pulley with b.s still inside the engine.
As a result the vibration which occurred at 3500 rpm only appeared at 4500 rpm.
- Installed stub shaft + new timing bearing
Vibration is now only 10% [ if you notice it very carefully ] as compared to balance shaft and that too at 4500 rpm.
No idle vibration
No humming
No vibration at 3000 rpm.
Still going through the running in process did 1200 kms, stub shaft installed after 1200 kms.

Things observed after stub shaft installation
- Oil pressure @ idle with balance shaft = 6 bar [cold]
- Oil pressure @ 100 C [ECT] with balance shaft at idle = 1.1 bar
- Oil pressure @ idle with stub shaft = 6 bar [cold]
- Oil pressure @ 100 C [ECT] with stub shaft at idle = 1.1 bar
- At 1500 rpm hot and cold with stub shaft oil pressure hits 3-4 BAR
- After the installation of the stub shaft RPM becomes smooth and throttle response is more crisp.
- Before balance shaft removal one of the lifters was making some noise but after stub shaft installation that noise has also become very less.
