Lost Seraph

I seem to have found myself in the possession of a large collection of event pokemon...Other than the trainer genders, they all seem legit. So, does anybody know the trainer gender of:

NWS 10017 Manaphy (mine has male trainer gender)

TRU 02089 Shaymin (also male trainer gender)

ALAMOS 05318 Darkrai (also male trainer gender)

Oblivia 03060 Deoxys (female trainer gender)

TRU 11079 Arceus (male trainer gender)

WIN2011 02211 Celebi (female trainer gender)

Are these right? Reason I ask is because I recently discovered how OT text color changes based on OT's gender. I'd hate it if I got screwed, but honestly it's not that big a deal because I was just trading Colosseum Jirachis for these, and I can always get more...

The pokemon without gender actually have an internal gender.

So using a gender modifying code on a Kyogre would pose no problems at all?

I need a nature modifying code (or multiple nature modifying codes) that do 2 things:

1) Do not affect gender

2) Applicable to Pokemon I've already caught (not wild Pokemon)

I can't believe this hasn't been done yet. Seems to me that it'd be more complicated to make a code that does gender and natures instead of making them separate, and that's the only one I can find; the gender & nature mod code.

I suppose I could live with the gender + nature modifier code if we knew the side effects it had upon using twice (example: turn a male jolly Horsea into a female quiet Horsea then back into a male quiet Horsea) especially for Pokemon that require a specific gender to evolve or Pokemon with no gender like 5/6 of my competitive battling team.

Is there a code to find out your secret ID in United States Soul Silver version that doesn't require the pressing of the L button?

EDIT: Nevermind, found it:

Wish I knew how to do this....alas, thank you kindly for making my code

I want an Action Replay code for a legit "MYSTRY" MEW and a legit "10 ANIV" CELEBI for Diamond version. If you could, can you put them in box 4 slots 29 and 30?
