Forms requirement and other questions

[gvazz]

Hi ALL,
Can you please help me with what forms should i send for
 Canada PR while applying for independent immigration from US?

I am applying the forms i downloaded from internet. Should i
  have to send 1 copy of forms IMM 0008 and IMM 5406 for myself
  and another same set filled by my spouse, and is this sufficient?
  I couldn\'t find the other form IMM 1052 (a typo?) as noted above
  in a response. Can anyone tell me the correct one if there is any.

Another question. The Buffalo instruction checklist asks for
   previous employer experince certificate detailing the salary,
   period of employment, job description, positions/time spent.
   I am no longer able to contact my employer in India as the
   company nolonger exists (4yrs back). I can get the required
   letters from later ex-employers. So my question is it sufficient
   if i show just a salary letter that employer? Will there be any
   chance of rejection? Should i enclose a letter that i cannot
   find the employer and hence i cannot enclose all the details.

Any inputs are appreciated.

thanks,
   G
