Jay, your a PADI diver I see, you can probably find the PADI videos on eBay but Im not sure how usefull you will find them as Im not sure what exactly you want, also as Devilfish says you cant learn diving by reading or from a video. You might wanna tell us approx how many dives you have done and how comfortable U/W you are so we can give you more specific advice. You mentioned some pointers on what to/not to do, quite a general thing but I'll try to break it down:
If you want to get more comfortable with your general skills (bouyancy, mask clearing stuff you learned at OW) take a Scuba Review at ur LDS, the instructor/DM can give you plenty of tips to fine tune ur skills.
If your talking about general dive planning and experience it might be wise to hook up with an experienced buddy and do some dives with them in a mentor kind of fashion, many ppl are more than happy to help out less experienced divers.
If you want to know what to know what to do when your up the creek without a paddle take a Rescue class, being a PADI AOW you could take the class as long as you have clocked up 20+ dives. You'll find many threads on here discussing different aspects and the benefits of rescue training so I wont list them all here. But IMHO all divers should take some form of rescue training. It will make you a much better buddy.
You mentioned some pointers on gear setup, there are many aspects to this that are constantly discussed (sometimes quite...passionatly) on this board. If you take a rescue class it will cover common equipment problems/failures and mistakes in setting up gear, and also how to deal with them. If your asking "whats the best place to clip my alternate air source" and other questions then these are the issues that are hotly contested on here. There are systems such as DIR (mainly used by cave/tech divers but still applicable to recreactional diving) that have a standard gear configuration and courses that offer answers to those types of questions. If this is what you wanted check out the DIR forum and see if its for you, its not to everyones tastes tho.
Jay,I hope this scatter gun type of response helps you as Im not entirely sure what you feel you need to learn/practise. Let us know and we can be more helpful.
