What is 装 and 连 doing in this paragraph about a newt in a glass from Matilda? E.g. 她再看那装着蝾螈的玻璃杯 This is from the Chinese version of Matilda (p.182):


  那蝾螈仍旧在那个高玻璃杯装的水里扭来扭去，看起来让人极不舒服。杯子对它来说太小了。玛帝尔达看着特朗奇布尔，她多么恨她呀。她再看那装着蝾螈的玻璃杯，恨不得跑过去把它拿起来连蝾螈带水泼在特朗奇布尔的头上。她想到她真这样做了的话特朗奇布尔会怎样对待她，不禁发起抖来。


The original English is:


  The newt was still squirming in the tall glass of water.  It looked horribly uncomfortable.  The glass was not big enough for it.  Matilda glared at the Trunchbull.  How she hated her.  She glared at the glass with the newt in it.  She longed to march up and grab the glass and tip the contents, newt and all, over the Trunchbull's head.  She trembled to think what the Trunchbull would do to her if she did that.


I understand it mostly, but don't understand the function of 装 and 连.
