Trying to get back in the game, few ?'s

Its been several years since I've attempted a brew. Unfortunately several of my batches were bad, from contamination or who knows what. Only one or 2 batches were palatable, and none were good :\

My equipment (plastic 5 gallon) has been sitting in the garage, it had some random dust and dirt on it...as well as some stain from when I was building a desk. The stain marks are really just at the top of the fermenting bucket, where the lid goes on. I believe I've gotten it all off. Should I worry about this or will it be alright?

Can anyone suggest a good basic ingredient kit to get me back in to the hobby. I'm not looking for anything complicated yet. I don't prefer beers like bud or miller. I tend to keep Dos Equis, Yeungling, and Sam Adams in the fridge. I guess I'm thinking maybe some sort of blonde ale would be nice...any suggestions?

I also have a basic question...I do have a wort chiller, I noticed after the wort gets to the correct temperature there is a lot of "stuff" settled at the bottom of the pot. Is all of that supposed to go in to the fermenter? or should I be trying to keep that out of the fermenter?

Thanks for any help!!

These seem like pretty easy kits to get started....As for the stuff at the bottom of your pot its ok to get a little in your fermenter but try not to get alot if any.

Buckets are cheap and it would be a good idea to get one in the 7 gallon range. Wood stains are nasty and even a small amount will mess up a lot of work.

As far as where to start, you might try AHB's Blonde Ale. Get the Safale yeast. It's a good dried yeast and you won't have to bother with making a yeast starter.

Keep the stuff out of the fermenter if you can.
