playing first fide rated tournament

Hi friends I am a passive chess player and I

haved played chess for more than 3yrs but

now I am willing to become a active

tournament player I have played few local

tournaments but now I am planning to play

my first rated tournament below 1600 and I

am eager to get rating I have 2 weeks left

for the tournament to start please give me

your valuable suggestions to get prepared

for the tournament as far as now I am

strong in white with colle zukertot but what

makes me worry is I realy don't have an

repoteri for black is there any similar

openings for black ku colle zukertot which is

easy to learn and less time consuming and

how should I prepare for tournament

concentrating on openings or tactics. time

control of the tournament is 1 hour each

and how should I use the time because I

generally play short games and I don't go

for coaching I prepare my self with chess

books ,videos and online game. please help

me out to solve these ptoblems
