Giggy - how tall are you, and how far from normal length for your height are your arms and legs? Also, try to give an accurate estimate of how far you typically hit your ~35-degree iron (either a 7- or an 8-iron). I stress accurate - not your single best shot with that club, not how far you are from the target when you use the club, not how you hit it with a tail wind (I know plenty of people who cite their iron lengths accordingly). In a calm, flat environment, with a typical swing, how far will you hit the ball with that club?
At the very least, we can give you an approximation for what the right fit is, at least in terms of length and flex.
Are they making your game worse? Probably not, unless they are horrible wrong for you (incorrect dexterity, extremely wrong flex, extremely wrong grip size -- the latter is extremely easy to fix, though). If our goal, without regard for money, was to make you the best golfer you can be, the first step would be to get you a new set of custom-fit clubs, and we'd probably go somewhere like Callaway's O.C. (CA) fitting center. Then you'd take a few lessons, and we'd re-evaluate the clubs, and we'd probably re-evaluate the clubs at least monthly. Needless to say, this isn't what I advocate, even on forums where golf takes the #1 priority.
Comprehensive fitting? Start with an iron fitting and ask them about a driver fitting. Irons are fundamentally important to be properly fit, IMO, since they are how you should be spending most of your full swing practice time (this avoids the question of short game practice vs full swing; that's another discussion for another time), and thus is how your swing will develop (again, we're comparing optimal to good, I hope; you aren't playing over-length X-flex, are you?).
As for the driver fitting... at least get the flex and loft right. IMO, the shaft length should generally be much shorter than off the shelf - again, this may be another story for another time. I use an AK grip with mine (I'm still using a driver I bought used - right specs other than length - many years ago; haven't assembled my own yet) because I haven't gotten around to cutting it down. I will next time I re-grip it.
