[quote name='binici']This would be ideal to complete the collection, but I heard part 2 and 3 really suck?[/QUOTE]
It's all subjective. For example, Roger Ebert liked every movie and gave each one three stars out of four, except for Fast and Furious which he thought was stupid.
But 2 Fast 2 Furious is part of the franchise, continuing Paul Walker's character. Plus characters from that movie do come back into play in later installments. Tokyo Drift is about whole new characters, and technically still hasn't taken place in the "timeline" since a character who died in it is upright and active in the next two movies.
