There are no one size fits all solution. A heavy tripod is needed for big lenses with an expensive head, yet a small one will do for a compact camera for an eBay photo. Current web forums favourite is a Gitzo GT3541LS, Markins M20 head and Really right stuff quick release B2 LLR II clamp. Also popular head choice is the Wimberley WH200 Version2 gimbal mount.
Deciding on a camera bag is a nightmare. Hundreds of choices and variations.
