Hi JessyB welcome to the forum. I myself have tried to apply for a tourist visa last year and was just lucky enough was granted one. I have provided them a Cert. of Employment, A Cert. of my leave for 3 weeks, Tax Declaration of properties, 6 months bank statement and the necessary documents needed from my sponsor. Aside from the documents from the sponsor the applicant must show evidences to the Embassy that there is a reason for coming back that is she has the job or family (if she has children). My sponsor had indicated in his letter the specific number of days he is inviting me to spend with him which coincides with his vacation at work.
With regards to your second question if you won't be accepted to enter the Phils. i think as long as there is no stamp on your passport "JessyB can't enter the Phils", then there is no problem.
Good luck.
