Hooked on Quilting

So, here's the quilt: It's pretty much directional, so do I quilt my motif (taken from the appliqued elements and quilt designed in AnS) in the outside border going all around or do I do the top/bottom the same as well as the sides or do I just quilt the motif around the quilt?  Better stated, do I treat it as a wall hanging and that I want to see the cars going across the quilt at both the top and the bottom? Or not? This is why I never get anything done.   Here's a pic of the motif (may be hard to see): I'm using the blue thread, just have to decide, help!!!!  I know, I know, it's my quilt, but I'd love some input. 

I'm struggling here.  I've never done anything black before (well, finished anything) and now it's loaded and ready to quilt. I'm going to mark the appliques and fill in the background with some sort of fill pattern. I now have a new machine AND Decision Paralysis. What do I do in the four-patches in between the applique?   I was going to use the truck, airplane, car from the pattern "On the Go" by Kariepatch Designs to make a quilting design for the black borders. Do I use black thread for just the borders or the white I plan to use in the center?  Help! Please comment if you've tried white thread on black and if it was something you'd do again. I'm so anxious to get started. It's basted and everything, just can't decide...

Here's my new HandiQuilter Infinity!!! It's ginormous.  I'm so excited and can't wait to do all my tops that have been hanging around.  I finally traded my old HQ16 in because I just couldn't sell it for what people wanted to pay for it. Nothing wrong with it and it had everything, just time to step up a bit. Loving it.  Here is the first quilt that I did on it last week. It's called "Snack Time" by Julie Herman. This is a close up of what I designed in Art and Stitch for the center hexagon. I did elongated loops in the triangles and fatter ones in the print hexagons. I also did the binding with the faux piping so it was all done by machine. It's the way to go, for sure. Even gifted already.
