If you use Shimano-compatible front brifter, then the cable pull ratio will be wrong for the front derailleur- MTB and road groups are incompatible in the front. But, you can use an 8 or 9 speed brifter in the rear while keeping the same derailleur- but if you use the 9-speed brifter on an 8-speed cassette, you'll need to do the "alternate cable routing" trick.

Top pull or bottom pull- the cable pull ratio is the same in the Shimano MTB groups.
