I am very comfortable with my work flow once I get into the groove and the fundermental reason I think this is because of how I lay everything out, its simple and everything I need is right there so I don't have to do work-arounds. Maybe this will help some people who are having writers block (what ive just got out a heavy case of..) or just those who still haven't found their feet when it comes to work flow..
Feel free to share your own guides, templates and plugins.
Plugins:The who, what, where and why
Most of the plugins will be freeware due to the simple fact, if you're looking to spend money you "should" know what you're lookin' for, though I will add payware alternatives if I feel there is those what are so much better than the freeware its worth shellin' out for. Please note though, a lot of payware plugins are designed for established/hobbyist/professional producers and sound designers who put a lot of money into music thus, meaning that if you're just starting out they will have a lot of extra things you either won't understand or won't use not to mention a (probably) noticable CPU increase from most freeware I will be posting, so please trust me when I say to use freeware and don't go pirating software just cause theres a price tag on it.
Master channel strip.
Smexoscope:VST and AU (Freeware)

This plug in is FANTASTIC my favourite freeware plug in there is because it cuts out a good 10-20 minutes you needed to bounce your track and check peaks, which could take you out of the zone.
What does it do:
Smexoscope shows you the waveform of what channel strip it is on, it tells you the DB where you hover your mouse over (so you can find where the peak is) show you weird phasing, weird-bendy waveforms and other stuff what you can only visually see sometimes. It also have a "amp" section which shows you what the waveform will look like turned up! (anyone else who used to suffer from a sample having nice transients till a certain boost of volume and only noticing when you bounce will never have that problem again!)
The viewing is also dynamic so if you're compressing/eqing/using a maximizer or something you'll see how the changes are working visually as you go along!
How to use it:
So, since the plugin shows what is playing on the channel strip it is on I put 2 instances of this on my master, why 2 instances you ask? The plugin shows either left or right (changable by clicking left or right, depending what its set on) and since its such a light weight plugin and a quite small (Gui wise) plugin, its possible to look at both instances at the same time.
So to actually use it once you've loaded the plugin up load a sound and press play, its really as easy as that!
Inspector: VST, RTAS and AU (freeware)

What does it do?
Everyone could do with a spectrum analyser and a more detailed peak meter as I feel most daws I have tried have shite peak meters and some don't have a dedicated analyser, most are built into EQs. Well Inspector does both and very well, you can set where you want Caution and Warning to pop up (as in, set it to -6db and it will go into the red when it peaks above, great for mixing down to Mastering-ready levels) which is a nice touch and its spectrum analyser is quite great.
How to use it?
Place this on your master, set your peak warning levels, save the patch and then you're sorted! have it on screen when determine levels and checking for unwanted frequencies and weird peaks.
Alternatives
I haven't found anything else what does this as lightweight and as well as Inspector so heres a few individual plugins what do the same job I will let you read up on the alternatives yourself, as I feel like ive tried to 'sell' you what I use and how it can help you but if you want to look at other options, heres some links

Drum Bus
Some people use them, some don't either way i'm just going to suggest a few plugins for drum bus usage, I am not going to explain how to use them as they're effects which you need to learn about on your own.

Rough Rider (win VST and os-x AU) (freeware)
I'm sure this is everyones favourite freeware compressor when it comes to adding colour, Rough Rider certainly has a great sound for getting some grittyness to your drum bus though it can make things sound "to" gelled together sometimes I find.
If you like Rough Rider is there a multiband version, which sadly comes with a price tag Rough Rider Pro
Buzcomp Free Bundle (Win only)
This is a quite old but very great freeware bundle, they're not very experimental and just do what it says on the tin.The Genecomp and Grancomp work well for drum buses and subtley gel everything together.
Buzzroom do, do a payware bundle which at 50$ I don't think is a totally bad purchase, having demo'd the bundle I can say you'd have to try it yourself as I feel it wouldn't suit everyones tastes. Click here to view
