Hmm.. I've been wondering. Maybe I should make a FAQ about (5th) Gen RNGing. Really a FAQ not a guide. So many of the same questions are being asked. I'm a bit shy when it comes to making a thread though, don't want to seem like a noob >.>
In the first window enter your seed where it says Seed (Hex) and choose BW Breeding. Now you can see inheritance and then you're able to find out if one of the inheritance patterns matches with that of your Venonat ^^
I totally like your Venomoth. I might test it against my friends ^^ Hmm... I'm not sure. Have you checked for a set already listed on Smogon or wishmkr? Butterfly Dance is such an awesome move and the fact that Venomoth can Baton Pass it totally makes my day! Imagine Venomoth passing two of those to Espeon! Stored Power will then have a BP of like 120/ 150 (+STAB!). They don't share the same weaknesses either I think. What a combo.. that's definitely worth trying!
Shiny breeding is way easier than shiny catching since it's so hard to get a low shiny frame when you haven't abused your PID. Check out the '4th/ 5th Gen Shiny Egg' Tab. It can actually look for seeds with the right IV spread and a shiny frame at the same time (so it'll give you a seed + the PID frame).
Bad IVs affect RNG breeding a lot since your baby mons will inherit three of the stats of it's parents. You can breed good parents though ;) That's what I did with my HP Fighting Eevee.
Yes, all three of them are DW and shiny and one of them is actually female too!
Actually RNGing stationary legends is the easiest thing to do (seriously, RNGing wild Pokémons are harder) because of course they don't have encounter slots. All you have to do is talk to them so you can save in front of them. You can use a synch for nature. The hardest part is actually finding yourself the right IV spread with a low shiny frame! Really, you shouldn't care about Pokémon being from the future 0.o
