Help with reading this Schematic/Board

I have this finished Schematic and Board files that have been checked and are working.
Now im trying to put them into a Perfboard and go from there.
Im confused about few things(lines) on this schematic.

First am i reading this right, these IC Pins are connected as follows:

DIL 5 to Mega 1
DIL 7 to Mega 19
DIL 8 to Mega 4
DIL 14 to GND
DIL 27 from R2 to Mega 16
from R1 to Mega 15
DIL Data Pins 22-15 to Mega 8,2,3,5,6,11,12,13 (8 pins) ALL Connected
DIL Address 13,12,11,10,9 to Mega 27,26,25,24,23 (5 pins) ALL Connected

Also the Ground do i have to connect it all Together? or just connect to empty pad?

I have attached the Schematic and Board files. Also on the Board file why some of the Data/Address thick lines are not showing? only showing on schematic?

thanks hope to fogire this out soon and put it into a perfboard

All grounds connect together.
All +5 connect together.
The blue lines are a bus where many wires travel together. (not all connected together) Normally each wire has a name where it enters and exits the bus. Because there is no hint as to which wire is which in the bus I don't know what to do.

Usually a bus has a name like A0:A7 and each wire has a name like A3 or A4 or A5.

ok i see..im using Eagle Cad..maybe its "hidden" within the schematic and i have to press certain button/function and the address/wires with names appear?
