1st of all due to budget constraints we are thinking to opt for fox 2.0 series air shocks.
I know it wl not come any near to float series but still...it should better than coilover in some aspects.
I have heard that such shocks are weak compared to coilover.
Site says
Maximum load capacity per shock, per corner, is 500 lbs.
 Does that mean that shock will fail if this much load exceeds?

No, it wont fail. We ran these shocks at 70psi without any issues.

The only "aspects" where air shocks are "better than coil over" are mass and quickly adjustable spring rate. This comes at the cost of coupled spring rate and preload, fixed progression, and much more complex re-valving.

If you've got budget constraints, and unless your car is down to 350 lbs, you should stick to coilovers. 
IMHO.

What was ur weight on wheel side with air shocks?

135 per front wheel, 195 per rear wheel. This was at the end of endurance with 175lbs of mud we didn't start off with.

Coil overs are probably going to be cheaper but then if you want to tune properly you are going to need a whole spring kit so that you can get your spring rate dialed in as opposed to simply adjusting air pressure.  And as far as re-valving goes its really scarier sounding that it is in practice.  Our suspension team has only been working with airs for 2 years and we had a fairly good handle on shock tuning.  Granted more time to tune would have been nice but we wasted the first part of the year tuning on walker evans nitro g air springs that we couldn't purchase anymore (discontinued) and then made the move to fox float 2's as they should be available for years to come.

We are thinking to buy Fox 2.0 air shocks..they are lot cheaper cost around 200$ per shock.
Any comments for 2.0 series?

What's more complicated about revalving an air shock?  I see some of the advantages to the coilovers in tuning, but the cost of purchasing a box of springs to eek out every inch of performance is likely going to trump the price of an air shock that weighs half as much.
