Please correct me if I'm wrong but book show that you can reduce C=O of aldehydes and ketones (not esters...etc Right?) to CH2 with wolff kishner/clemmensen, but some books also show that it is possible with H2/pd.

But wouldn't H2/pd reduce it to alcohols? or does it only reduce aromatic C=O to ch2?
Please can someone clear this up? Thanks alot

Aromatic C=O? Whats that? Do you mean benzaldehyde, bensophenone etc.?
You can reduce carbonyls by hydrogenation and if the carbonyl is alpha to a aromatic ring I guess you reduce it further to a CH2. I have never used this, I think its not very common.
