I'm basically in the same position (i.e. I'm new to taping and asking really basic questions) so here is basically a layman's terms version of what people will probably say:
First: NO! A good portable (as all of them are, more or less) setup can get great sounding recordings, and can be relatively inexpensive.
From what I've found from people around here, is that mic quality and LOCATION are two key factors for a good recording. (along with remembering to hit "record"

)
The R-09HR seems to be a really good beginner recorder (I just bought the old R-09), but the internal mics are definitely not preferable to use to tape a show. So that's definitely a good foundation to a decent rig, but for higher quality recordings you probably want to invest in some quality external mics.
Which leads into your Sony mics. From a brief check they don't look like the best for a live show. You might be able to get something decent with those into your R-09HR but the setting would pretty much have to be perfect, so that will be a LONG shot if you're looking for anything really listenable that you'll feel proud of.
From what I've heard (and invested in) Chris Church makes reasonably priced quality mics. Seeing as I've joined the CA team I don't mind advertising at all. He's got crazy deals as seen here:
http://taperssection.com/index.php?topic=130844.0But that did come from good recommendations: I knew I was going to make the plunge and buy some (relatively) inexpensive gear and here are some good answers to a cheap but quality rig:
http://taperssection.com/index.php?topic=132722.msg1740241#msg1740241OH, and that brings us to your next question. Seems as though the golden rule is LOCATION, LOCATION, LOCATION. If you can find the "sweet spot" (generally running over peoples heads (6-7 ft high) DFC (Direct F#$king Center) at the point of an equilateral triangle with the predominate amps) you'll be good to go. Some good Cardioid mics in the right positions (DIN, ORTF, split, whatever, you can look those configurations up) in the right spot and above the crowd will really reduce the crowd noise. Just wikipedia "Stereophonics" for basics (or search the boards here).
Here's a really good place to start for general mic info too. Read carefully! If you're really trying to figure it out, make sure you got a general grasp of this and go from there:
http://www.churchsoundcheck.com/micsarecool.htmlAnd as far as cleaning up a poor quality pull, it seems that you're better just scraping (or putting aside somewhere

) rather than attempting to try all sorts of stuff that won't help too much. Sort of a live and learn approach.
So, thats a very basic version of what I've gathered from around TS. Sorry, its a little long winded for little info, for a beginner (like myself) its the foundation I've assembled from how to get into the game. Last thing I'd add is to ASK QUESTIONS! This is a great community and seem more than helpful with anything.
And if you're at a show, find a taper and ask (before/after the show, or during set breaks of course

) about his rig, where to fly your own from, or anything else...or just buy him a beer
