Print problems with last three motions (PLA)

Hello, I tried printing a "poker chip" (11-layer) and a small calibration stick (3-layer) in PLA the other day and run into the same problems every time.

Problems:
1) The filament has a hard time grabbing the blue tape initially (tried hairspray, didn't seem to change anything). It usually globs up for the first two inches and I have to pull it off of the plate/extruder side. I'm using a 5mm skirt, and it globs for both the skirt, as well as the actual print. This results in a small bump in the first of two perimeters, which either pulls up the perimeter on second pass, or creates a weird effect in the print (IMG_6228).

2) When the print is finalizing, the extruder seems to "ignore" the last three motions (IMG_6229 and IMG_6230). Doesn't matter what I'm trying to print.

Settings:
Layers:
0.3mm height, 100% first layer
2 perimeter, randomize starting points, generate extra perimiters when needed
Horizontal layers: 2 top, 2 bottom

Infill:
0.4 fill density
rectilinear fill pattern
infill every 1 layer, solid infill every 20
fill angle 45, solid infill threshold area 70mm^2
only retract when crossing perimeters

Speed:
perimeters 30
small perimeters 30
external perimeters 70%
infill 40
solid infill 40
top solid infill 30
support material 40
bridges 40
gap fill 20
Travel for non-moves 130
first layer speed 30%

Skirt and brim:
loops 1
distance from object 5mm
skirt height 1 layer
brim width 0

try using concentric infil. Something about rectilinear does that.
