1. You need to do some research about what components to consider buying.
I load mostly handgun--so I cannot speak authoritatively on both your cartridges--but I did start learning .223 about a year ago.
To learn what others have done, google is your friend--i.e., use search terms such as "loading .223" or "loading 25-06" in google to search a specific forum, not the internet.
I'd also look at more than one forum--for example, google on the net to find a rifle reloading site, besides this one.
That will get you some basic information.
In my case, my LGS owner is a .223 reloader--so I simply followed his advice and bought 100 pcs of new .223 brass, some WSRs, and some H-335. (I already had some 55-gr. FMJs).
Keep in mind that the internet resources are good for reading, but not for new loader use, necessarily. So, plan on buying at least one manufacturer's manual, and also order / pick up the "free" recipe handouts from powder or bullet manufacturers.
2. As for buying resources--start with your LGS, if they are reloaders, not salesmen. If that isn't a reliable source, then for on-line buying I would recommend 1) Powder Valley, or 2) Graf & Sons.
There are scads of other component suppliers; search the threads here for those discussions.
Finally, if I were in your shoes I would also post a list here of your proposed equipment purchases and let others critique it. The "general information" about reloading--the comments that don't track for rifle-versus-handguns--can be confusing. The workflows are sufficiently different that you may not need some items, but definitely need others.
You can get good honest feedback here, in this forum--so make use of it and, as nicholst55 said, ask detailed questions.
The only dumb question is the unasked one, and if you have no questions because you think you have these fundamental issues sorted out, then you might reconsider....
