For most basic electronics....
1.5mm & 2mm desoldering braid. (I use 'gootwick' brand- works very well)
20-50 watt soldering iron.. Assorted tips if you can, otherwise about 2mm is good.
Rosin Core Solder.. maybe 0.7-1mm for electronic compoments.. and around 2-3mm for automotive wires... dunno the brand, same large roll now for around 5yrs. (no label...)
Flux pen... use very rarely.. tip has dried out...but still use a diabetic syringe to extract and use occasionally.
Checkout Youtube.. there are some fantastic vids on techniques for soldering all mana of things.
Where to buy..well I use ebay alot now... sometimes the quantities supplied can be misleading on the cheapest stuff..but generally as good as anywhere else.
Or visit your local electronic store and ask the 'experts'.
