Hi there,
Yes, if you breed two albinos of the same strain together you will produce all albino babies. There is no guarantee that they will be better-looking than their parents (you should, however, go to Tremper's site and read his "Temperature affects colour" page).
They do not need a lot of space or time to breed, IF the female is receptive to the male's advances. You can use a separate tank if you wish, but it may not be necessary. Watch the female closely when you put them together - if she runs away from the male, or struggles when he approaches and bites her, you will need to separate them and try again later (in a few days). Be prepared for some violence, because even normal mating can look very rough. The male will bite the female repeatedly, tugging at her and climbing all over her in order to get into position. As long as she accepts this treatment, leave them alone!
I keep all of my leos in separate tanks except for breeding. I've tried putting females back with the male a couple of days after breeding, and again after laying a few clutches (i.e., in mid-season) to see if they were receptive to repeat breeding. None of mine have been receptive so far. One breeding per year appears to be sufficient, in their opinion! But then again, others keep their animals together all the time with equal success. Individual animals (and keepers) differ.
Glad to hear you do have the Leopard Gecko Manual. It is a valuable resource. I hope you have also read a few care sheets and perhaps done some searching in the forum archives - there is a lot of information available for you to use. For example, it is important that you properly prepare and maintain your breeding female (she must be at least 9 months old and 35 grams - I prefer to have my females 10-12 months old and over 40 grams before they breed).
Hope this helps.
Regards,
Amy
