When landscaping the front of home, it would be in the context of the whole front, not just the center section. The information one needs is of a swath that goes from left side lot line to right side lot line ... roughly illustrated in this picture:

I took the pictures from where you suggested, but it seemed like the tree was blocking the front of the house (hate that they planted a tree right in the line from the door.) I also included a set of photos taken from the other side of the tree in the next post.

The other set of pics.

I can't tell you how to use all of the plants you have, but can make suggestions about where you could use what type of plant. You can determine, of what you have, what makes sense to use in a given spot. If you want to update, I would definitely not use any plants as an edging stripe around the perimeter of a bed. Something like the "variegated grass" which is probably Lirope or Mondo, would be much better used as a solid groundcover. There's quite a few places you could use such a thing. The "grass" could be divided and you would have an ample supply for some use.

I dislike the tree in line with the front door, too, and would make it disappear. Would raise the canopy on the birch to at least above the eave height. The low hanging branches give a disheveled look. The bed by the mailbox would look much better if it was a true quarter circle. Where it intersects the curb and drive it should meet at 90*, not any other angle.

I brought the bed out around your swing. It shouldn't be directly in the lawn. If the picture cooperated, I probably would have put another small tree off of the right front corner of the house. It would help frame your house, screen the view of the neighbor's house and give the sense of some shelter for the swing.
