Shields appear to only effect incoming things.Franchise: Star Trek Series: The Next Generation Season: 3 Episode: 26 Title: The Best of Both Worlds Part 1 wrote: SHELBY: Mister La Forge has a plan to modulate shield nutation. Hopefully, that'll hold them off for awhile.
LAFORGE: At the same time, we'll be retuning phasers to higher EM base emitting frequencies to try to disrupt their subspace field.
Even with failing shields, diving into a normal star is relatively safe.Franchise: Star Trek Series: The Next Generation Season: 5 Episode: 1 Title: Redemption Part 2 wrote: KURN: Maintain course. Status of warp engines? Warp engines at fifty percent. KURN: Status of shields?
WORF: Aft shields buckling.
KURN: Transfer auxiliary power to shields!
WORF: Aft shields are gone! We cannot win. We must withdraw.
KURN: Keep your place! New course. Three zero seven mark two seven five.

KURN: Maintain course.

Some forms of shielding use subspace technology, but this is unusual.Franchise: Star Trek Series: The Next Generation Season: 6 Episode: 22 Title: Suspicions wrote: CRUSHER: That's why I went to the Altine Conference. I'd heard about a new subspace technology developed by a Ferengi, a Doctor Reyga.
GUINAN: A Ferengi scientist. Hmm.
CRUSHER: His invention was based on metaphasic fields, but his methodology was completely unorthodox.
Again, shields being subspace systems appears to be rare.Franchise: Star Trek Series: The Next Generation Season: 7 Episode: 9 Title: Force of Nature wrote: PICARD: What's the origin of this debris field?
DATA: Unknown, sir. It does not appear in any Federation charts of the Corridor.
PICARD: Could it be what's left of the Fleming?
DATA: It is a possibility. The debris consists primarily of duranium and polycomposite fragments which suggest a ship. Furthermore, the field contains sufficient mass to account for the Fleming.
PICARD: All right, let's take a closer look. Perhaps we can find something that will give us a more positive identification. Helm, take us through the debris field, ahead slow.
DATA: Captain, I am picking up a small metallic object, approximately three point five metres in diameter.
RIKER: Could be a ship's log recorder, or a probe casing.
DATA: I do not believe so. It is emitting an unusual signal. Captain, it is beginning to generate a verteron field.
PICARD: Shields up! Full reverse. Now! (a sound, then the lights dim)
PICARD: Damage report.
WORF: Warp engines are offline. Shields are down. All subspace systems are inoperative.
RIKER: Just like the Ferengi ship.
DATA: Unidentified ship heading toward us. Two life forms are aboard.
PICARD: On screen.
DATA: Captain, they are initiating their transporter system.
PICARD: Can we get more power to the shields?
WORF: No, sir.
RIKER: All decks, security alert.
DATA: Captain, we are being boarded.

Transporters are generally not useable when deflector shield are in place.
http://www.startrek.com/database_article/metaphasic-shield wrote: New type of shield invented by the Ferengi scientist Dr. Reyga in 2369. A metaphasic shield is a series of overlapping low-level subspace fields, which causes the shielded object to partially exist within subspace itself. The first test of the new shielding was in 2369 when a shuttlecraft from the U.S.S. Enterprise NCC-1701-D was outfitted with the shield and piloted into the corona of a nearby star. The test was apparently unsuccessful, but Dr. Beverly Crusher proved that the test had been sabotaged by the pilot as part of a plan to discredit Dr. Reyga and steal the shielding technology. A second test proved that the new shields did function correctly.
http://www.startrek.com/database_article/shield-inverters wrote: Part of the shield array systems on Federation starships. In 2368, the U.S.S. Enterprise NCC-1701-D used its shield inverters as part of a plan to remove ionized plasma from the atmosphere of planet Penthara IV.

Enterprises shield effectiveness against the Borg. This only temporarily worked though as the Borg ships were able to overcome the effects in just a few short minutes.
