not sure if your friend has already done this speech or not...and right now i don't have the time to read thru it all, but at a glance...straight away the first sentence is not needed - it is merely repeated in the second.
And the poets name is SKRZYNECKI - I don't know if this will help but our teacher taught us to remember it by;

Its also a little hard to cut down a speech for someone else since everyone speaks at a different pace - i suggest your friend...or anyone... finds a document - typed up - of a few pages long. Read through it and then do it again, the second time timing your self - when your at 3 1/2 mins. stop and mark it on the page. Then you know roughly how long your speech should be.
Keep in mind, the you will vary your speed when presenting your speech in front of your teacher and peers.
