i'm just learning asl, as of yesterday, so i close my eyes when i fingerspell or i speak when i sign (the few phrases i know) is that considered rude?
Keep in mind that for sign languages (being visual) that closing your eyes while signing (espeically in a conversation) is the equivalent of plugging your ears while talking/being spoken to ... so in that respect - yeah, it is rude and something you need to make a conscious effort to not do. If you have your eyes closed it means that you're cutting yourself off from communicating with the deaf person (which may be construed as ignoring them).
A good example that might help you understand why it's a habit that needs to be broken is: it's common for Hoh/Deaf children who don't want to "listen" (obey) their parents/caregivers/teachers etc to
close their eyes because it simultaneously prevents the child from "hearing" (aurally or visually) what is being said AND prevents the parent/caregiver/teacher etc from being able to TELL them anything!
As such - closing your eyes may seem to some like you are unintentionally screaming "I'm not listening, I'm not listening"
Speaking while you sign - is an indication that you're not actually learning/using ASL since the word/sign order in ASL is completely different than English grammar (which makes doing both together effectively impossible). People who speak and sign and the same time are using a mode called CASE or PSE ... it stripes ASL of it's grammar and tries to impose English word order into ASL - it's very common for students to do this when they are learning because they don't yet understand ASL grammar (and that ASL is in most ways as different from English as French, Spanish or German is.
What I'd suggest trying instead of closing your eyes to concentrate that instead you take a moment to THINK in English word/phrase for what you are wanting to express (spoken or signed) - and then sign it linking the PHRASE you think to the PHRASE you sign (trying NOT to think "this sign = this word" while you're doing it)
If you've taken another language - maybe French, Spanish ? before ... it's the same thing that you try to do when using those languages (ASL is grammatically similar in maybe ways to French if that info helps)
If you're looking for some good books that explain ASL grammar here are a few I'd recommend:
A Basic Course in American Sign Language (Second Edition) which is a "must have" if you're learning on your own - and is available from:
DawnSignPress (you can place the order online - or by calling them directly)
Direct link to the book on the DawnSignPress website
It's also available from Amazon (make sure to get the 2nd edition and the spiral bound version as it is MUCH easier to work out of and costs less!!)
Amazon.com: Basic Course in American Sign Language: 9780932666420: Tom Humphries, Carol Padden, Terrence J. O'Rourke, Frank A. Paul: Books

The other book, also available from Amazon that is fairly good for learning ASL sentence structure/grammar is called
http://www.amazon.com/American-Sign-Language-Easy-Way/dp/0764134280/ref=sr_1_1?ie=UTF8. Some of the signs used in the book are not the "best" - however if you use it as a grammar guide and look to [ame="[URL]http://www.aslpro.com/cgi-bin/aslpro/aslpro.cgi[/URL]"]aslpro.com[/ame] etc for the actual signs it can be very helpful ... as an intro text.
I hope that helps - if you have any specific questions let us know, and feel free to PM me if you want !!
