Firstly I have not caught any sharks. But have done quite a bit of research into this area.
The most popular spinning reels seem to be
shimano big baitrunner
[b:3dvyyls2]Penn [/b:3dvyyls2] (Slightly cheaper then the Shimano Baitrunners)
Okuma Axeon 90
There are other reels around which would do a good job. The high end Shimano Stellas or Daiwa Saltiga reels would be excellent but they cost around the $1000 mark
With regards to line weight, 30-35lb seem to be a common suggestion. There are plenty of ‘popular’ brands out there. Just avoid the ‘very cheap stuff’ made in Malaysia or China. I am going to spool my reel with 38lb Pioneer Flexline. But there are lots of ‘brands’ to choice from.
