Is there an easier way to do placement/rotation?

I’m currently doing the Unity 3d tutorial, and have gotten to the part where I have to add the particle animators to the player’s jet packs.

Unfortunately, I can’t seem to get the hang of using the translation and rotation tools. No matter what I do, I can’t get rotation to the point where the flames actually go down. It’s really hard to see what direction the flames are actually traveling in, since what looks like “down” from one point of view is completely wrong from another…

As I rotate, the position seems to change as well, getting strange numbers like -1.639128e-06.

As I get the positioning so that it looks like the flame is directly under the jet, rotating my view shows it completely off. If I try to adjust it to look right, and then move around the scene, it’s way off again =/

Is there some tool or something that helps with placing an object relative to another?

Also, is there a way to get the builder’s view to circle around the object I’m working on? It seems to rotate around some point far in the distance, which is very counter-intuitive when trying to look at a single object from different angles.

rotation/position:
use the orthographic views (click on the icon arrows in the top left of the viewport)
(else you will spend all day adjusting transforms)

object viewing:
select object
move cursor into viewport
press F key
now the view will rotate around it
(this is one of the most important things to know when first using Unity ;))
