Hi,
Dont cut the coils. You need to lower it a bit so you can have a nice look. The answers to your queries are as follows:
Handling experience:   Handling will be better
Ride comfort:             Ride will be bumpy 
Which brand to go for: Go for Any good brand like neu speed lowering spring/ TIEN etc, otherwise shock absorber can be damaged
Price range:               around 10K 
and any other overall pros or cons...: suspension bushes will wear out quickly
people already using them..please do post your experience.
also posting current pics with current height.
You should lower your ride to give it a v nice look. I am using TIEN lowering springs with KONI Yellow shocks with CUSCO pillow ball mounts on them. It has adjustment of soft/hard on the fly. They are superb also the ride is superb but i spent hell amount of money on this. 
For further queries, pl feel free to ask.
