Here's a tip.

If your model has lots of objects that makes it hard to pick and modify objects/curves/etc in your perspective view, you may find it useful to hide any un-necessary objects.

Select everything your want to hide with Ctrl + h to hide em

OR (if you want to save time)

Select the objects you want to work with and hit:

Alt + h

...to hide an inverse selection. Which keeps the things your want to work with and hides everything else.

Hit Ctrl + Shift + h to un-hide the last set of hidden objects.

I use these hotkeys all the time.
