Here is some advice that I found about level 58; I found this advice on the Big Fish forum for the game. Does this help at all?
Use the top section to keep charging up to the Tesla hammer and each time you get it, use it to break whatever color has chains on it at the bottom. After the chains are gone, either use the regular hammer or the Tesla hammer to get the pieces out
and:
Don't waste your time powering up to the Bomb or Fireball. Just use the hammers to remove the tiles on these two rows - I use the single hammer on tiles of only 1 color (ex: 1 blue), and the powerup hammer on tiles that have several (ex: 3 yellow, or 2 red, etc).
Also, try to make matches of 4 or more tiles on the upper board - you'll powerup faster (get used to using the 4 or more strategy...it will help you on other boards).
