effects alot of people say no Boss and i agree with them...boss sucks tone, non true bypass and just sometimes is just a nusense with the mark.
Well, yes and no. It really depends on a lot of things. In general, true bypass has certain advantages but if your pedalboard only contains TBP pedals, you could run into impedance issues - which in turn results in even worse tone. For a more detailed explanation, see http://www.petecornish.co.uk/case_against_true_bypass.html
(Pete Cornish, if you don't know the man, has built very high-quality and very, very expensive custom effects boards for guitarists like Brian May, Cat Stevens, Robert Fripp, David Gilmour, Andy Summers, Gary Moore, Tony Iommi, Jimmy Page etc. All without true bypass. He is considered something of an expert on this matter.)
As for Boss, I think that the made-in-Japan Boss pedals are actually quite good for the price. They have been used successfully by many guitarists you are probably familiar with, see http://guitargeek.com/search?qt=g&q=boss and click the links for famous rigs that contain Boss pedals.
But whether they fit your sound and style, that's another topic. Like with all gear, try to test them with your amp and guitar before buying.
I can't really recommend any "essential effects". It all depends on the kind of music you play, whether you are a rhythm and/or lead guitarist, your personal preferences, your band, and so on. I own a whole bunch of pedals, from expensive boutique ones (that cost as much as a small amp) to typical simple/cheap pedals - I have been buying them since the 1980s - as well as digital multieffects units, but I have removed almost all of them from my regular live board. The wah pedal was the last to go. It was pretty good but I almost never bothered to use it live. The only two pedals I still have left in my regular live board are very modest and inexpensive ones:
1) a Visual Sound Route 66 comp/OD: Chinese built but sturdy, bowever, the compressor side makes some extra hiss which could be a pain in the studio but does not really bother you live (it drowns in the band mix). I'm using this because it gives me even more sonic options (the OD and compressor can be switched on/of separately, and there are also some voicing switches, like the switchable bass boost for Tube Screamer clone OD side which can otherwise be a bit high-mid heavy, just like the traditional Tube Screamer). It also enables me to back down the amp gain and then kick in the pedal for extra sustain or gain.
2) a Boss delay pedal in the effects loop: not the best sounding delay pedal I own but it has turned out to be the most reliable - which is pretty much the
most important thing in a live situation
