Hi Sophie Welcome to the forum.Your sticky coins can be sorted by a quick soak in pure acetone (not nail varnish remover) easily found cheaply on ebay. After a soak a quick flush in distilled water then rest on kitchen roll to aid a dry.The acetone will de gunk your coins with no other harm.
2x2 self adhesive flips are great for storing run of the mill coins.You can also get album sheets which take 2x2 flips.
A great little book for British coins is Collectors coins GB published by Chris Perkins (the owner of this site).
Spinks coin book is another great resource.The 2018 edition is now due but you can buy earlier copies very cheaply.Try Amazon.I update my Spink about every 3 or 4 years.
These are great little albums.You can probably get them cheaper if you search around.

I don't know where you are based but a trip to the Midland or Wakefield monthly coin fairs will open your eyes (google both)
Walk before you run,set up a spread sheet for your records and enjoy.
