By habit, I have positioned my clickies on the right of my character, on the presumption that the companion would take a position on the left. This is the behavior of the pets in World of Warcraft.
A little experimentation shows that pets don't behave this way in StarWars TOR. When you change your position, companions path to the closest point on a half circle behind you.
o x o
* *
*z*
If they're coming from behind you, they are likely to stand right behind you(z) and obstruct your clicking.
If they're coming from in front of you, they'll choose one of the side positions(o), which might leave your clicking clear if the clicky is on the other side.
Just face your companion, and step back one tap.
If repositioning the companion this way doesn't work for you, another idea is to keybind the camera controls. ZoomIn, click, ZoomOut. I recommend F and V.
I do not recommend fighting in first-person cam (many effects do not appear, such as your own gunfire).
When you visit a crafting trainer, by default you only see the items you can craft with your current crafting skill. So, new items will appear there when your crafting skill reaches higher level.
But you can let it show all schematics (including those that you can't craft yet) by choosing "All" instead of "Trainable" in the dropdown in the upper right corner of the window. This way, you can find out what level of the crafting ability do you need to craft the better items.
In the screenshot above, you can see that I have chosen "All", so that even schematics that I can't craft yet (that require level ≥ 380) are visible.

Unfortunately there has never been a way to collect all of the equipment for all of your (1-50) companions.
Now that companions do not require gear at all to function in combat (besides a weapon), it seems that there is no way to get these old alternative outfits for companions specifically besides their default outfit.
