Welcome to the wonderful world of beagles!!
These little guys are fantastic energetic dogs!
two and a half years ago was my first ownership of a beagle and they are smart learn fast.
We initially got my little boy and we also worked long and odd hours and he got very lonely and would hate us leaving in the morning, so we got him a little girl they are great friends however mine both had a love of undies especially ones that had been on you for the day!! Thankfully they are long out of that stage now.
The best first book I found for them was Beagles for dummies it was a great book and talks about all the things that you are after.
With the toilet training this is about your dedictaion. During the night when my dogs were young 8 to 12 weeks I set the alarm and would get up every couple of hours to toilet them and then when they were in the process of their buissiness I would reapeat wees wees wees (ok it makes you sound a little crazy to the neighbours), but let me tell you it does not take too long beofre you can take them out and say the magic word and they will associate it and do their buissiness.
I would also recommend taking her to puppy classes it is great for socialisation and also basic command things sit, lay down etc!
My dogs have a toy box and they are welcome to do as they please with their toys but if I find them chewing anything that is not theirs I remind them that their toys are what they chew on (Say a strong no to what they were eating and take them to their toys and encourage them to chew them) This seemed to work and they now forrage through their toys and destroy at will.
I hope this helps
