Need help to formulate a research design


I am trying to find out the factors that effect the users adoption of internet banking. I have prepared a questionnaire and have been suggested by some that Partial least square (PLS) will be the best method to analyze it. Can anyone suggest if PLS will be the most appropriate analysis technique or not? And if you can also help me how should i start analysing using PLS (how i can analyse using PLS). I had used a 5 point likert scale in the questionnaire (please check the attachments). And if possible can i use SPSS for this or not. There are 7 determinants, namely, intention, Attitude, Perceived Behavioral Control, Subjective Norms, Perceived Usefulness, Perceived Ease of Use and Trust.
