The answers before were good, but let me add some explanations.

First, always write nouns with a capital Letter in the beginning, Like "Wochenende", "Sommer" and "Boston". (You'd even spell "Boston" with a capital B in English.)

Then, you mixed up the prepositions quite wildly:
"zu Hause" is "at home", indicating the place where you are. The correct preposition to indicate a direction in which you move is "nach".

I'm not quite sure what the first sentence was intended to mean. Did you mean you have to stay at home? Then "zu Hause" would be correct, but the word for "stay" is "bleiben": "Ich muss dieses Wochenende zu Hause bleiben." Did you mean you have to go home this weekend? Then "gehen" is correct, but the preposition must indicate direction, so it would be "nach": "Ich muss dieses Wochenende nach Hause gehen." -- Please also mind that Germans use "gehen" only in the sense of walking. When using vehicles, they specify it by the verb: "fahren" (to drive / car or train) or "fliegen" (to fly).

Knowing about the meaning of "nach", the next sentence is clear: "Ich fahre diesen Sommer nach Boston". (Use "fliege" if you take a plane.)

The third sentence can be improved by capital letters and the use of German umlauts. Maybe you just didn't find them on your keyboard, but don't worry: ?� can be replaced by ae, ?? bei oe, ?? bei oe, and the hated ?? by ss. Every German knows that, as there are no umlauts used in crosswords, so the German h?�??lich ("ugly") becomes haesslich. And looks haesslich if spelt that way.
Third sentence thus: "Ich esse jeden Morgen Br??tchen zum Fr??hst??ck", or, on an American keyboard, "Ich esse jeden Morgen Broetchen zum Fruehstueck".

Next one: "brauchen" und "gebrauchen". "brauchen" means "to need". "gebrauchen" means "to use", but is mostly used in phrases like "Das kann ich (gut) gebrauchen", "I can make (good) use of that". The word you were looking for is "benutzen": "Ich benutze jeden Tag den Computer", where you could improve the phrase by changing the word order: "Ich benutze den Computer jeden Tag" ("daily" or "every day", as stating the time, goes to the end of the sentence. There is a word in linguistics for that specialty of the German language, but I forgot it.)

I cannot make any sense out of the last sentence. Did you mean, "Let's meet on friday for a coffee at your place"? "Kaffeetrinken" (in one word) is a German ritual like the British five o'clock tea; but it's not restricted to coffee. In reality, in can involve some beer or booze. "Ich trinke diesen Freitag bei dir Kaffee" maybe was what you meant. "bei dir" means "at your place" or "at your home". "bei dir zu Hause" would also be correct. ("bei" requires the Dativ, third case.) -- "Let's meet for a coffee on Friday" would be: "Treffen wir uns am Freitag zum Kaffeetrinken?".

Hope I could help.
