I have the same camera and housing (D7000 and hugyfot) and a lot (too many...) of strobes. First advice is to strongly reconsider optical connection because it is more reliable and a lot cheaper (you can save around 100€ or more to your budget if you go optical).
I have subtronics, seacams, sea&sea 250 pros and YS d1s and, for your budget, I would choose either second hand YS 250 pros (there are people selling them because of weight at around 1000 - 1200 € for two) because they are very good for WA (but don´t have S-TTL ), or new D1s which you can buy two within your budget and are lighter, have S-TTL for macro and, although not as powerful, they can do the work for most of the WA situations... Inon Z240s are also a safe bet.

I've used both D7000 and D800 for supermacro side by side and it is much more difficult with the D800. I think in the above example, DOF is the same but FOV will be different. Holding FOV constant, the DOF will much much narrower on the D800. The more I read about the issue more confused I get by the physics behind it, but in practice I don't think there is much question.
FOV is where the trick is: we can fill the whole image in a 7D with a 23mm shrimp at 1:1, but that shrimp in FF camera at 1:1 will have a lot of surrounding area. In order to get the same image of the SAME subject we have to go 1.5:1 and that will reduce the depth of field...
About manipulation: The contests rule almost always state what you can and cannot do. There are even some contests with different categories for manipulated (unrestricted) or unmanipulated (restricted) photos like OWU. You can enter the same picture in as many contest as you want as long as, at the time of entering, it has not earn any prize. Once the picture has won anything important, you will have to read the next contest rules to see if they allow prized pics or not.
About rights: read the rules. I do not enter any contest where the rights go beyond "only using the winning pics to promote the contest etc..." some contest even keep the rights of all the entered pics (whether they win or not!!!)
I have both (Inons) and, if you dive a lot, get the 45š because you will get used to it and framing will become second nature. If you donīt dive regularly get the 180š because it will be a great improvement from the start.
