Go to Cocona Village and continue left until you reach a forest. Then find your way north to find the entrance to Rasp Cavern, make sure to capture some Pokemon on the way through the forest though, because there are some Pinchers guarding the entrance.

It is Mukrow you can get him by hitting a tree outside of the RIGHT entrance to rasp cavern on Renbow island, I think you need 1 or 2 Tackle to do it might pay to check. Hope this helps!
Suicune's monument is in Canal Ruins. However, if you are doing the quest from Weber, the other monuments are in Daybreak Ruins and Rasp Cavern. However, for Raikou's Monument, you have to get a fragment from someone at the top of Mt. Layuda.
If you have the monument piece than you go to Raikous monument and get near it. If you don't have the monument piece than you go to Rand's house and do the first part of the paragraph.
