Filename2 10296 xxx Date: 09/05/08
Filename3 10296 xxx Date: 09/08/08

output is:
Filename1 xx
Filename1 yy

Repeating values is also fine:

Filename1 xx 10296 xxx Date: 09/01/08
Filename1 yy 10296 xxx Date: 09/01/08
Filename1 Total 10296 xxx Date: 09/01/08
Filename2 xx
Filename2 yy 10296 xxx Date: 09/05/08
Filename2 zz 10296 xxx Date: 09/05/08
Filename2 Total 10296 xxx Date: 09/05/08
Filename3 xx 10296 xxx Date: 09/08/08
Filename3 Total 10296 xxx Date: 09/08/08

if you have Python
Code:
d={}
for lines in open("file2"):
    lines=lines.strip().split(" ",1)
    d[lines[0]] = lines[1]
for lines in open("file1"):
    lines=lines.strip().split()
    if "Total" in lines[1]:
        print lines[0] , d[lines[0]]
    else:
        print ' '.join(lines)

output:
Code:
# ./test.py
Filename1 xx
Filename1 yy
Filename1 10296 xxx Date: 09/01/08
Filename2 xx
Filename2 yy
Filename2 zz
Filename2 10296 xxx Date: 09/05/08
Filename3 xx
Filename3 10296 xxx Date: 09/08/08

With AWK (use nawk or /usr/xpg4/bin/awk on Solaris):

Code:
awk 'NR == FNR { 
  t = $1
  sub(/[^ \t]* /, "")
  _[t] = $0
  next
  }
($1 in _ && /Total/ && $0 = $0 FS _[$1]) || 1
' file2 file1
