Welcome to the forum! Many of us have been where you are right now, so in my opinion there are no bad questions and the more you ask the better. This is a great place to ask them as well, there is lots of help here. My suggestion would be that it is early on in your relationship with your birds, and they are unsure of who you are and what that means for them, so grabbing and forcibly using a towel would not be advisable until they trust you more. Doing it too soon may actually damage the relationship with them. I would either hold off on the baths for a little while until they trust you more, or if they stay in the cage when you open the door, just place a large bowl on the floor of the cage and let them bathe in the cage. You don't need to dry them with a towel, they will dry themselves quite easily.
As for the male female thing, dominance does not necessarily mean that one is a male, they could both be either male or female and still have this. The only way to know for sure is to have them DNA tested, which might be a good idea if they are sharing the cage. Otherwise you could have eggs in your future!
For taming, if you are feeding any kind of seed mix as part of their diet, watch after you replace the bowl which seed they go for first. Then next time you fill the bowl, pick out all those seeds and use them as treats. Or try some small pieces of nut or fruit to see what they like and will take from you. Easiest way to start, after just sitting and talking to them to get them used to your presence, is just by providing the treat whenever you approach the cage to talk to you. That way they start to associate you being around with good things happening. After that is established, start with target training while they are inside the cage (there should be a post on this in the Taming and Training list). Once they are good at that you can start to let them out by targeting them onto your hand (best to do this one at a time).
The more they come to trust you that you are not going to hurt them, the more they will let you do. Go as fast as the birds will let you, not faster. It sounds from your post like these two have not had a lot of socializing in the past, so you need to start small to establish trust.
Good luck! Let us know how it goes
