custody questions and steps needed

[junm9477]

first off just wanted to say im glad i found this forum.

here's my situation:

last weekend my fiace served me with a TRO (temporary restraining order) which states i cant see my 2 yr old daughter till the order is lifted by the judge. court date july 9th.

im currenly preparing my custody case by myself (cant afford a lawyer)

weve been together for 6 yrs. she has 2 kid form her previous marriage. i helped her thru her divorce from a abusive ex and custody of the kids. i paid for all court and attorney fees.
since she moved in with me 6 yrs ago i supported her and her 2 kids due to school ( then kids was 4/5 yrs old) she didnt work even to this day

2 yr ago we had a child Hannah.  

the first 5 1/2 yrs evrything was fine the following month due to economy and kids having more needs we had arguements. once a month if not less.

there was no physical voilence just all verbal arguements. there was a time in march due to frustration i punched the wall.  but never once even motion to hit her.

our last arguement was in april agian verbal no physical contact whatsoever.  her son called 911 said he got scared beause of the shouting but by the time the police came we were working it out. there were no police report or arrest made.

already filed a the custody paper work. but would like to be prepared when i see the judge.

btw: she lives only 2 miles away at a relative place now

sorry its long

my question or input:

what informations do i need to gather before the court date?

i asked for mediation already on the paper work.

also we are in california
