Your panther looks mostly like an ambilobe. you need take some better pictures of him maybe in daylight and get him fired up to really tell.
i noticed the pictures of your veiled with the eyes closed looked like they were taken when it was dark maybe she was woken up from sleeping? the last few pics in your gallery that look bright like they were taken in the daytime and her eyes look much better.
for the rest of your questions you might want to post another thread since this one is for a panther ID. you would probably get a lot more responses if you posted in the breeding section

i can give you a quick rundown though.
i use a 5 gallon bucket for egg laying. i only have experience with panthers but for them i use 8-10 in of dirt/sand mix is fine. use only dirt that is
fertilizer free as in organic dirt. peat moss can also be used. for sand use play sand. mix the sand and dirt together around 50/50 you will have to moisten it so that when it is throughouly mixed you can poke a hole in the mix that will not cave in if you shake the bucket a little. its should be damp and humid not wet. you dont want it too wet or it will become too compacted and make it harder for your cham to dig.
for the shower put her in the shower for 20 minutes with the water on only one half of the cage so your cham can come and go as she pleases. some chams dont shower willingly so you will have to see.
like i said before you would be better off posting a new thread this one should be kept to IDing your panther. you will have a very good chance that one of the experienced veiled keepers will help you with all your veiled questions if you make a new post. i am also sure this topic has already been addressed numerous times and you can probably find the answer to all your questions with a quick search.
